Outline of Final Research Achievements

The objective of this study is to realize an electrically driven light emitting device by forming electrical connection in a semiconductor-based three-dimensional (3D) photonic crystal, towards 3D photonic and electric integrated devices. After designing the 3D photonic crystal, the 3D nanostructure was fabricated by a novel micro-manipulation method under optical microscope observation. The performed optical measurements on the electrically connected 3D photonic crystal showed the quantum confined Stark effect and cavity mode for a nano-laser. This is the first demonstration of electrical connection in a semiconductor-based 3D photonic crystal.
