Abstract: The effect of a weak optical feedback on the power and spectral parameters of light-emitting modules based on near-IR quantum-well superluminescent diodes (SLDs) is studied. It is shown that even very weak parasitic feedback (k_fb<-30 dB) distorts the emission spectrum of high-power SLDs and noticeably reduces their output power.
