1550nm 25mW PM SLD Laser Diode

This laser is a broadband SLD operating in inherent superluminescent mode. Unlike traditional ASE-based SLEDs, which produce narrower spectral bandwidths under higher drive currents, this superluminescent characteristic enables it to generate wider spectral bandwidths at higher drive currents. Its low coherence reduces Rayleigh backscattering noise. Combined with high power and broad spectral width, it mitigates photodetector noise, improving spatial resolution (for OCT) and measurement sensitivity (for sensors). This 1550nm SLD features a 14-pin butterfly package and meets the requirements of Bellcore document GR-468-CORE.
