Photonic-crystal slab absorber and high-frequency circuit and electronic components, and transmitter, receiver and proximity wireless communication system

摘要

The photonic-crystal (PC) slab absorber includes: a two-dimensional (2D)-PC slab composed of semiconducting materials; and a lattice point periodically arranged in the 2D-PC slab, the lattice point for forming resonant-state which can capture an electromagnetic waves incident from an outside by resonating an electromagnetic wave in a band edge of a photonic band structure of the 2D-PC slab in the plane of the 2D-PC slab. The 2D-PC slab is doped with impurities and can absorb the captured electromagnetic wave in the band edge resonant frequency of the 2D-PC slab.

1. A photonic-crystal slab absorber comprising:
a two dimensional photonic crystal slab composed of semiconducting materials; and a plurality of lattice points periodically arranged in the two dimensional photonic crystal slab, each lattice point for forming resonant-state which can capture an electromagnetic wave incident from an outside by resonating an electromagnetic wave in a band edge of a photonic band structure of the two dimensional photonic crystal slab in the plane of the two dimensional photonic crystal slab, wherein the two dimensional photonic crystal slab is doped with impurities and can absorb the captured electromagnetic wave in the band edge resonant frequency, wherein an amount of impurities doping level of a surface portion of the two dimensional photonic crystal slab is higher than an amount of the impurities doping level of a portion of the two dimensional photonic crystal slab other than the surface portion.
