Abstract :
A theoretical investigation of the high-speed coupling phenomena of two laterally coupled diode lasers (LCDL) is presented. The analysis is centered on the spatiotemporal dynamics of the LCDL when coupling between emitters is varied, We have obtained the dynamic behavior of these devices showing high resonance frequencies beyond the well-known resonance frequency of a single diode laser. In this paper, we have presented a new modulation scheme by asymmetric switching of the injected current in both stripes, showing short optical output pulse modulation with a high repetition rate
