Abstract:
1. A terahertz-wave connector, comprising: a two dimensional photonic crystal slab; lattice points periodically arranged in the slab, the lattice points for diffracting terahertz waves in photonic bandgap frequencies of photonic band structure of the slab in order to prohibit existence of the terahertz waves in a plane of the slab; a two dimensional photonic crystal waveguide disposed in the slab and formed with a line defect of the lattice points; and an adiabatic mode converter disposed at an edge face of the slab to which the waveguide extended, the waveguide extended to the adiabatic mode converter, wherein the adiabatic mode converter, in a planar view of the slab, may have a tapered shape so that a tip part becomes thinner as being distanced from the edge face of the slab, and a side surface of the tapered shape has an inclined plane.
