Paper Abstract

We have developed ultra-broadband Super-Luminescent Emitting Diodes (SLEDs) at 840 nm with a 3-dB bandwidth of 45-75 nm. The SLEDs show high robustness against back-reflections of up to 50% with little change in coherence length, sidelobe suppression ratio and secondary peak suppression over a wide range of back-reflections. First long-term measurements do not show any signs of device degradation. Hence, these SLEDs can be employed in OCT systems without costly broadband optical isolators.
