New compact Broadsweepers and optical power boosters for OEM applications.

Superlum has extended its product line of tunable wavelength-swept "Broadsweeper" lasers to include new compact models intended for OEM applications—BS-790-1-OEM, BS-840-1-OEM, and BS-930-1-OEM. The high-resolution acousto-optic tunable filters used in these lasers ensure high accuracy of wavelength control in static operation and excellent wavelength repeatability in sweeping operation. The size of the laser unit (including all control electronics) is only 110 × 41 × 190 mm (W × H × D). The optical power of lasers is 3 mW and it can be boosted up to 20 mW by stand-alone, plug-n-play, spectrally-matched optical boosters of the same footprint. The height of the boosters is 31 mm. The tuning and sweeping range is from 55 nm to 110 nm depending on the model. A wide tuning range exceeding 200 nm can be obtained by combining all three models by appropriate fiber couplers. Newly designed electronic controllers ensure reliable day-to-day operation without adjustments. For detailed information about the new line of tunable lasers and power boosters, click here.

The newly introduced light sources, cBLMD-D-890-UBB-HPPDF (38 KB) (12 V DC-powered) and M-D-890-UBB-HPPDF (38 KB) (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-TO56PDF (74 KB) 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, notably speckles.

New high-power multimode fiber pigtailed SLD modules SLD-M381, SLD-M341 and SLD-M531PDF (42 KB) 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.

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 Boosting of SLD Power. Feedback-Insensitive, Ultra-High-Power MOPA SLD SourcesPDF (119 Kb).

SUPERLUM Ltd. have changed its name to Superlum 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 available.
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 DWDM devices.

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 upon request).

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 soon.
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 quantities.
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 high quantities.

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.
