Abstract
We present a simple ultrashort optical pulse generator based on step recovery diode, short-circuited transmission line and relaxation oscillation effect suppression with reduced dc bias. Experimental results achieved a 80-ps optical pulse with 655 nm AlGaInP laser diode (LD) and a 200-ps optical pulse with 420-nm GaN-based LD.
