摘要

Three different nanostructured semiconductor lasers were studied - the quantum dot passively mode-locked laser, the dual-mode quantum dot laser, and the optically-injected quantum dot distributed feedback laser. The key milestones achieved were: (1) the use of external optical feedback to reduce the timing jitter of the pulsed lasers from 295 fs/cycle to 32fs/cycle; (2) experimental determination of the optimum temperature range and absorber-to- gain length ratio; (3) Delay Differential Equation modeling to study the nonlinear dynamics specific to the quantum dot medium, including the derivation of new equations for this purpose; (4) the demonstration of dual-mode lasing in a quantum dot distributed feedback device using optical injection to generate microwave, mm wave and THz signals; and (5) the generation of relaxation oscillations over a continuous 5 octaves (below 1 GHz to 40 GHz) in an optically-injected quantum dot laser.
