New Modular Broadsweepers and Optical Boosters for OEM Applications.
Superlum introduces new compact Broadsweepers (swept-wavelength tunable lasers) for OEM customers.
With a footprint of only 110 × 190 mm, the new devices have the same functionality as our benchtop Broadsweepers,
thus becoming highly attractive for integration into customers' equipment.
The akinetic design of the external cavity with a precisely stabilized acousto-optic filter ensures excellent repeatability of
the wavelength setting while tuning and sweeping. The laser output can be boosted by a stand-alone optical power booster of the same footprint.
Both units are 12 V DC-powered. The units can be controlled from a PC/Laptop and can also be switched on and off by a TTL-level signal.
Preliminary specifications for 840-nm devices are
already available. Custom combinations of tuning range and optical power are available upon request.
New uncooled single transverse mode free space SLDs in 780 – 920 nm range.
Superlum has expanded its product line of uncooled single transverse mode free space SLDs in 780 – 920 nm range.
The following new models has been added: TO-9 canned medium-power modules with an output power of 20 mW at
and 30-mW TO-56 canned SLD modules at 850 nm.
These reliable high-brightness low-coherence light sources can be a good replacement for laser diodes in applications
suffering from speckles and other kind of system noise associated with narrow spectrum and high temporal coherence of laser diodes.
New SLDs at 670 nm with record-breaking performance.
Superlum announces new SLDs at 670 nm with record-breaking performance. Two new models are commercially available:
15-mW uncooled TO-9 SLD-260-HP-TO9-670
and 10-mW SM/PM fiber coupled butterfly packaged SLD-261-HP2-670.
Moreover, Superlum is finishing the development of ultra-high-power single mode SLDs at this wavelength.
Preliminary ratings are 25 mW in free space (SLD-260-UHP)
and 15 mW ex SM/PM fiber in butterfly packaged SLDs (SLD-261-UHP).
Both free space and fiber coupled modules are already available in small quantities.
New generation of cBLMD-series compact broadband light source modules with extended bandwidth.
Superlum has introduced the second generation of
cBLMD series of multiple-SLD light source modules with extended bandwidth.
A key advantage of the new generation of cBLMD light sources is that the drive current of each SLD can be controlled individually,
making it possible to tailor the optical spectrum to meet customer requirements.
New product lines of made-to-order single-SLD light sources.
Superlum has significantly expanded its portfolio of made-to-order single-SLD light sources,
allowing customers to choose a product that best fits their needs. The new offerings include 9-30 V DC-powered
mCS-series modules with a fiber pigtail, sCS-series modules with an FC/APC socket, CS-series modules with
an integrated optical isolator and other components, and 12 V DC-powered cBLMD-S-series modules
with digital control of SLD parameters.
New ultra-wide-spectrum SLD modules.
Ultra-wide-spectrum SLD modules belonging to the UBB-series are now commercially available. The modules are available at 830 nm
having a 6-dB spectrum width of 85 nm), and at 930 nm (SLD-471UBB
having a 6-dB spectrum width of 115 nm). The modules are butterfly packaged and SMF or PMF pigtailed.
Free-space modules are available upon request. While targeting ultra-high resolution SD-OCT as the main application, these SLDs can be successfully used in
a wide range of other types of optical sense and measurement systems.
New ultra-broadband SLDs and SLD light source devices.
Superlum starts offering UBB-series (ultra-broadband) of SLDs and SLD light source devices. The main design goal was
to cover the maximum possible spectral range by the minimum number of SLDs while preserving acceptable spectral flatness
within the 6-dB spectral range around central wavelength. The newly introduced light sources, cBLMD-D-890-UBB-HP
(12 V DC-powered) and M-D-890-UBB-HP
(AC-powered benchtop), provide a 6-dB spectral width of 190 nm with
a spectral flatness better than 4 dB. UBB-series SLD modules providing a 6-dB
spectrum width of 80 nm at 830 nm and of 100 nm at 930 nm will also be
added to our product list very soon.
Superlum expands its product lines to include new free-space and fiber coupled SLD modules.
New low-cost SLD-380-MP-TO56
module is now available at 830 nm. The important advantage of this SLD is nearly elliptical far field pattern.
This allows direct replacement of laser diode modules in free space systems for reducing undesirable parasitic effects caused by laser diode temporal coherence,
New high-power multimode fiber pigtailed SLD modules SLD-M381, SLD-M341 and SLD-M531
are available at 840, 855 and 1065 nm center wavelengths.
These devices can be very helpful for low-speckle optical illumination for various applications in photonics where multimode fibers are used
for delivery of light. These SLDs are characterized by reduced sensitivity to optical feedback, compared with single mode SLDs.
A new model of Broadsweeper BS-930-1-HP with extended wavelength-tuning range.
Superlum is pleased to introduce a new model of a high-power wavelength-swept laser, the Broadsweeper BS-930-1-HP with
an extended wavelength-tuning range. The laser is built on the use of a quantum-confined SOA and a quasi-collinear AOTF
in an external fiber ring cavity. The device has demonstrated the full tuning range of up to 135 nm at the output power of
15 mW that is the best result ever shown for rapidly swept lasers in 880 – 1010 nm spectral range.
The device can sweep the emission wavelength with a sweep speed from 2 nm/s to 104 nm/s.
The laser offers the end-user different modes of operation — the manual sweep mode, automatic sweep mode, external sweep mode and
two-wavelength switching mode. The model provides high spectral and power stability of laser emission both in time and in temperature.
High spectral tuning accuracy and reproducibility together with strictly linear emission frequency sweep in time are ensured.
The device is equipped with a PM-fiber output that guarantees high values of PER of laser emission (> 20 dB).
Thanks to these advantages of the developed model over the existing BS-930-1, this new swept source can find
its place in a variety of applications requiring high-power laser emission together with rapid wavelength
tuning over a wide band of wavelengths covering 880 – 1010 nm. To the best of our knowledge, the new model of
the Broadsweeper considerably exceeds the existing analogues.

MOPA-SLD-850: The first commercial 850-nm SLD-based benchtop system emitting 50 mW from PM-fiber with a smooth, low-rippled optical spectrum.
Superlum is pleased to announce a new achievement in developing of high-power SLD-based light sources, namely,
the first commercial 850-nm SLD-based benchtop system emitting 50 mW from PM-fiber with a smooth, low-rippled optical spectrum.
The design is based on the "SLD MOPA" approach described in the corresponding application note. It is 100% PM-fiber-based and
provides stable output polarization with PER of 20 dB at the fiber output. In addition to very high optical power, there is another important
advantage of the "SLD MOPA" design, namely, its reduced sensitivity to optical feedback (see the application note for more details).
The instrument may be used in various applications requiring very-high-power and low-coherence single-transverse-mode light sources,
for example, Optical Coherence Tomography and white-light interferometry, spectroscopy, metrology, low-speckle optical illumination,
optical imaging and others.

Superlum demonstrates 50-mW SLD-based light sources with low sensitivity to optical feedback.
Superlum announces that it has achieved record-breaking power levels for SLD-based light sources.
The light sources utilize Master-Oscillator-Power-Amplifier (MOPA) configuration in which the light from a medium power master SLD is amplified by an appropriate semiconductor optical amplifier (SOA) of the same wavelength.
The use of MOPA system allowed us to demonstrate a light source at 840 nm with an output power of 50 mW ex SM-fiber and a spectrum width of 15 nm, while still having a negligible spectral ripple. An important advantage of the light source is its reduced sensitivity to optical feedback.
For more details on the new light sources, please refer to our new application note

close the gap between 770 – 1160 nm and 1270 – 1600 nm
spectral ranges of conventional SLD-based light sources.
Superlum introduces a new product line of light sources for OEMs, called
S-series Broadband Light Source Modules. These modules have the same
optical parameters as AC powered benchtop S-series Broadlighter devices, but were designed
for integration into optical coherence tomography (OCT) systems.
Medium power SLD-26-MP modules at 680 nm are divided into two subcategories,
based on output power. The first subcategory, the "MP1", corresponds to the former
MP category of SLD-26 modules. New modules with higher output power (up to 2 mW ex SM fiber) make up the second
subcategory, the "MP2". Free-space MP2 diodes have output power ranging from 3 mW (minimum) to 5 mW (maximum)
at +25 °C. This change allows our customers to choose medium power SLDs
that better meet the requirements of a particular application. It also provides
cost savings for customers looking for medium power SLDs at 680 nm.
The specifications were updated to reflect the change:
A variety of fiber coupled SLD modules in 1000 – 1100 nm spectral range are available now:

Diodes, Ltd. Due to increased sales, we have rented additional
250 sq. m for carrying works on design, development and
control of superluminescent diodes – the heart of our modules.
1480 nm and 1550 nm SLD modules are now commercially
Modules provide up to 2 mW SM fiber output and have excellent, low-rippled
spectrum. Devices may be extremely inetresting for testing of fiber-optic
components, including Er-doped amplifier components and passive
SLD-48-MP are now available at 1045 nm.
Since October 2000 SLD-48-MP diodes are available at 1045 nm center,
with 50 nm FWHM low-rippled spectrum. Output power from SM fiber
pigtail is 1 mW (up to 2 mW may be delivereded
SLD-47 series provides more than 7 mW SM fiber
output with 70 nm FWHM at 950 nm band.
Since October 2000 we are offering SLD-47-HP category with greater than
7 mW SM fiber output at 940 nm range.
New packages available. In October, 2000,
in addition to existing packages, we provide: double-sided butterfly
package, 5.6 mm TO cans, and a new miniature 'MINIBUTterfly' fiber
package (10 × 10 × 4
mm frame size).
SLDs cover more wavelengthes in range from 1480
nm to 1560 nm.
As a result of design efforts at this band, SUPERLUM is now offering
engineering quantities SLD modules rated from 0.5 mW to 2.5 mW ex
SM fiber output centered at 1480 nm, 1530 nm and 1560 nm. The device
ratings will be finally added to our Web Site by the end of July.
However,you can ask us on any detail right now.
SLD-26, 680 nm series diodes are now more powerful.
SM fiber output up to 20 mW, and free space outputs up to
40 mW are now available. Maximum residual spectral modulation depth
is now rated to 3%, twice less than before! In addition, devices
are now divided into different power categories, allowing our customers
to select devices that match their requirements better and safe
budget when very-high-outputs are not necessary. Considerbaly lower
priced, 3 mW free space, 1 mW ex fiber,
SLD-26-MP category is now available.
1480 nm SLD modules will be available
SUPERLUM is planing to offer commercially 1480 nm - centred
SLD module prototypes starting from mid February 2000. Modules will
have 1 – 2 mW SM fiber output with about 50 – 55 nm
FWHM and a small spectral modulation depth.
SLD-56-HP series diodes with up to
5 mW ex SM fiber output are available in engineering
This is the result of our efforts for the further improvement of
1300 nm SLD emitter, as well as the coupling method.
PILOT-2 drivers are now available
with possibility for setting and indication of SLD driving parameters.
New compact drivers, when supplied by 9 V DC, provide
excellent stability and protection of SLD modules, with idication
and setting of SLD current, temperature and monitor photocurrent.
New PILOT-2 drivers may be used with any of SLD module
produced by SUPERLUM Ltd.
SLD-36 series diodes are removed from our product
list. The substitution to the old module is SLD-38-MP
diodes, 3 categories with the same ratings as SLD-361
A, B, C. Main advantage of 38-MP diodes is longer lifetime:
MTTF greater than 100000 hours at +25 °C is already
confirmed, target value is 200000 hours (SLD-36 diodes
has a MTTF of 60000 hours). Another advantage is lower prices at
Such specific wavelengths as 780 nm, 808 nm and
920 nm are now available with our superluminescent diode modules.
Improvement of 1300 nm diodes has resulted in
increased outputs of SLD-56 series devices. Now three categories
of diodes are available, rated typical 0.5, 1.0 and 2.0 mW ex SM
fiber output power.
Soon, 0.5 mW Ex fiber 1550 nm band prototypes
will be available.
On April 1999 new version of our PILOT drivers
will be commercially available. The main advantage of the new driver
is a possibility to control SLD current and temperature and their
changes. It is also planned to add indication of SLD current, thermistor
resistance and monitor photocurrent.
