The SLD-CHIPS-A-A82-W1590 series is a broadband SLED that operates in a true inherent superluminescent mode. This 1590nm Superluminescent Chip on Submount superluminescent property generates broader band at higher drive currents in contrast to other conventional SLEDs which are ASE-based, where high drive tends to give narrower band. Its low coherence reduces Rayleigh backscattering noise. Coupled with high power and large spectral width, it offsets photoreceiver noise and improves spatial resolution (in OCT) and measurand sensitivity (in sensors). The SLED is available in Chip on submount package. It is compliance with the requirements of Bellcore Document GR-468-CORE.
