Abstract:
1. A semiconductor device comprising: a two-dimensional slab photonic crystal structure including a substrate supporting a sheet-like slab layer including, sequentially stacked, as stacked layers, a lower cladding layer, an active layer, and an upper cladding layer, and that has a periodic refractive index profile structure in surfaces of the stacked layers, the periodic refractive index profile structure introducing a linear defect region serving as a waveguide, and, optionally, a dielectric layer or a solid semiconductor layer on which the sheet-like slab layer is stacked and held; and a p-type region and an n-type region in the slab layer with a pn junction surface at a predetermined angle with respect to the surfaces of the stacked layers in the slab layer.
