摘要
The effects of etching a shallow surface relief in the top mirror of an oxide confined vertical-cavity surface-emitting laser, for the purpose of selecting the fundamental mode, have been investigated by numerical simulations, A quasi-3-D model has been implemented which self-consistently accounts for optical, electrical, and thermal effects, The design has been optimized for maximum single fundamental mode output and the limiting mechanisms have been studied. The results are also compared with experimental values and the effects of limitations in fabrication precision are investigated.
