Abstract

We present unidirectional emission from strained InGaAsP multiple-quantum-well quasistadium laser diodes, whose resonators consist of two confocal end mirrors and two long, straight, sidewall mirrors. Far-field patterns exhibit highly directional emission at a 20° angle from the cavity axis. This angle corresponds to a unidirectional ring trajectory inside the resonator. We also report that the unidirectional emission can be explained by the phase locking of two resonator modes with different symmetry classes based on the extended Fox-Li mode calculation method.
