Abstract :
Summary form only given. Typically, a passively mode-locked semiconductor laser is implemented with a saturable absorber, which provided pulse-narrowing mechanism. In this paper, we demonstrate numerically a passively mode-locked semiconductor laser based on nonlinear directional coupling in a coupler consisting of two parallel traveling-wave semiconductor amplifiers. In such a nonlinear directional coupler, the coupler length is chosen to be nearly a coupling length (one-half of a beat length).
