All-optical memory based on the injection locking bistability of a two-colour laser diode

This paper presents a multi-quantum well InP/InGaAlAs two-colour Fabry-Perot laser that incorporates slotted regions in the laser ridge waveguide. A hysteresis loop of the output power in the uninjected mode as a function of the power injected in the long-wavelength primary mode . Pulse modulation of the injected power leads to switching between these states. To understand the structure of the bifurcations that lead to the observed bistability, a model of a single mode laser with optical injection is adapted.
