Surface-emitting laser with two-dimensional photonic band structure embedded by wafer fusion technique

Summary form only given. The photonic band structure (PBS) has been drawing much attention to control light emission and/or propagation. To realize the PBS in the optical wavelength region, we have proposed utilizing a wafer fusion technique between submicron-order patterned wafers. Furthermore, by this technique, the integration of PBS with a light-emitting layer is also possible, and the realization of novel opto-electronic devices is expected. Recently, we have developed a light-emitting device with two-dimensional (2D) triangular-lattice structure (TLS) embedded by the wafer fusion technique and have shown the very unique surface-emission pattern, which reflects the 2D photonic band nature of TLS. In the work, we demonstrate for the first time a room temperature (RT) lasing oscillation of the surface-emitting laser with 2D PBS embedded by the wafer fusion technique.
