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

摘要

We study the injection locking bistability of a specially engineeredtwo-color semiconductor Fabry-Perot laser. Oscillation in the uninjectedprimary mode leads to a bistability of single mode and two-color equilibria.With pulsed modulation of the injected power we demonstrate an all-opticalmemory element based on this bistability, where the uninjected primary mode isswitched with 35 dB intensity contrast. Using experimental and theoreticalanalysis, we describe the associated bifurcation structure, which is not foundin single mode systems with optical injection.
