Spike and Double stability on QDSEL of positive and negative optoelectronics feedback 220 ps

Abstract

Abstract Nanotechnology laser is one of the fastest growing areas in many fields of science and medical applications. In this study, the behavior of quantitative point semiconductor laser was studied (quantum dot semiconductor laser QDSL) with positive and negative optoelectronic feedback (OEF) utilizing the rate equations to investigate the behavior of the delay time and its effect on the density of the photons as the values of the optoelectronic feedback were changed by the value of the time (τ = 220 ps). Many different regions of stable and double spike when optoelectronic Feedback Strength values as ζ = (+0.2)−(+0.6) and ζ = (−0.2)−(−0.6).
