ABSTRACT:
A reverse current transmitted through an initially forward biased step-recovery diode causes the step-recovery diode to switch from the forward biased state to a reverse biased state, thereby developing an abruptly rising reverse bias voltage across the step-recovery diode. The abruptly rising reverse bias voltage is applied across a series combination of a capacitor and a laser diode, connected in parallel with the step-recovery diode to force a short, abrupt forward current pulse through the laser diode, thereby causing the laser diode to emit a short optical pulse.
