Abstract
The THz-wave device comprises: a 2D-PC slab; lattice points periodically arranged in the 2D-PC slab, the lattice points for diffracting the THz waves in PBG frequencies of photonic band structure of the 2D-PC slab in order to prohibit existence in a plane of the 2D-PC; a 2D-PC waveguide disposed in the 2D-PC slab and formed with a line defect of the lattice points; and an RTD device disposed on the 2D-PC waveguide.
