M-S-series BroadLighter. Benchtop Broadband Light Sources.

Product description

Superlum M-S-series BroadLighters, the second generation of our S-series BroadLighter light sources, are high-power, very wide spectrum and low coherence AC powered benchtop light sources based on a single mode fiber coupled superluminescent diode modules (SLDs) of Superlum.

Features

  • Very high output power exceeding 30 mW in selected models
  • Wide optical spectrum
  • Short coherence length
  • Changeable output power
  • -30 dB peak optical isolation
  • Models with optical attenuators
  • Remote control through USB or by TTL
  • Wide input range power supply unit (100-240 V AC)
  • Two years warranty

Changing output power

Superlum offers two types of M-S BroadLighters, namely, with and without a Variable Optical Attenuator (VOA). The former has the suffix "-VA" in the model number. In both designs, output power is changeable within 0–100% with the step of 10%. Spectral performance is guaranteed at the full (100%) output power.

In M-S-series light sources without VOAs, the optical output power is changed by varying the SLD drive current, entailing a change in the shape of the SLD spectrum. The change is not significant for models with a bell-shaped spectrum but may be large for models with a complex, multi-humped spectrum (see the examples below).

Spectrum of BroadLighter M-S-795-G-I-15
  Spectrum of BroadLighter M-S-795-G-I-15. Left – optical spectrum at output levels: 100% (20 mW SMF, black line); 50% (10 mW SMF, blue line); 10% (2 mW SMF, red line). Right – same but normalized: 100% (black line); 10% (red line).  
Spectrum of BroadLighter M-S-840-B-I-15
  Spectrum of BroadLighter M-S-840-B-I-15. Left – optical spectrum at output levels: 100% (20 mW SMF, black line); 50% (10 mW SMF, blue line); 10% (2 mW SMF, red line). Right – same but normalized: 100% (black line); 10% (red line).  

In M-S-series BroadLighters with VOAs, SLD itself always emits 100% of its power. The output power is changed with the help of a broadband VOA that is placed after the SLD module and the optical isolator. For these BroadLighters, changes of optical spectrum with output power are negligible (see the example below). As a rule, Superlum offers M-S-series light sources with VOAs when the light source is based on an SLD with multi-humped spectrum. However, M-S-series devices with VOAs and SLDs with bell-shaped spectrum are available upon request. M-S-series light sources with VOAs are recommended for applications requiring changeable output power but stable spectral shape and center wavelength.

Spectrum of BroadLighter M-S-840-B-I-15-VA
  Spectrum of BroadLighter M-S-840-B-I-15-VA. Left – optical spectrum at output levels: 100% (15 mW SMF, black line); 50% (7.5 mW SMF, blue line); 10% (1.5 mW SMF, red line). Right – same but normalized: 100% (black line); 10% (red line).  

Optical isolator

All standard light sources have an appropriate built-in optical isolator to protect the SLD from optical feedback.
