Abstract

3-dimensional(3D) photonic bandgap crystal is very attractive for the realization of thresholdless light sources because of controlling the lifetime and the radiation pattern of spontaneous emission by forming the localized impurity mode in the absolute forbidden band^[1-3]. We proposed novel surface emitting laser diode consist of a 3-dimensional(3D) photonic bandgap crystal cavity^[4]. The spontaneous emission is controlled to radiate into the lasing direction with narrow radiation angle by introducing a plane phase shift region into the photonic crystal. In this report, we for the first time show uni-directional radiation of the spontaneous emission from a 3D photonic bandgap crystal cavity laser by using a plane-wave method.
