Paper Abstract

A theoretical study of the control of the high-speed modulation of Two Laterally-Coupled Lasers (TLCL) is presented. The analysis is centered on the spatio-temporal dynamics of the TLCL when strength coupling between emitters is varied, depending of the distance between emitters and the carrier diffusion level. We have controlled the high-speed chaotic dynamics through the injection current, studying the temporal evolution of the relative phase between the fields of the two stripes. After controlling the high-speed dynamics, we have obtained a modulation scheme by asymmetric switching of the injected current in both stripes, which gives an output pulse modulation with a high repetition rate.
