Importance of self-induced carrier-density modulation in semiconductor lasers

Abstract

Semiconductor lasers have a built-in mechanism for modulating the carrier density at multiples of the longitudinal-mode spacing. This mechanism is believed to be relatively unimportant for solitary laser diodes since the mode spacing typically exceeds 50 GHz. A general numerical model capable of including self-saturation, cross saturation, and four-wave… (More)
