Abstract

We describe the mode switching operation of multielectrode strained InGaAsP multiple-quantum-well quasistadium laser diodes. Far-field patterns exhibit highly directional emission along the laser cavity axis for current injection at the axis electrode and highly directional emission at angles ±19° from the cavity axis for current injection at the ring electrode. These directions correspond to the axis mode and the ring trajectory mode of the laser cavity. We also succeeded in obtaining single peak output beams using narrow curved end mirrors of 40 μm width.
