Abstract :
Pulse-code amplitude modulation of GaAs double hetero junction lasers has been achieved at subnanosecond rates by series connecting laser diodes with bistable Gunn-effect switches. Laser-intensity risetimes down to 200 ps and falltimes to 400 ps have been obtained when pulse-code switching occurs between high and low phasing levels.
