According to the principle of carrier diffusion, we fabricated an electric pattern high power single quantum well broad area semiconductor laser. The designed devices have special current injection stripe which forms Gaussian-like photon gain laterally. Utilizing this principle, tailored gain lasers exhibiting near single lobe far field patterns were found. The tailored gain lasers emitting at 808...
Free space laser communication becomes one of the most attractive research pot of next generation optical communication technologies due to its advantages of large data transmission amount, high directionality of transmission and high transmission security. The tapered semiconductor lasers are one of the most important optical sources in such systems. In this paper, we introduce the structure design,...
