Optical Properties of Asymmetric Transmission Devices for One-Dimensional Photonic Crystals

Abstract

In this paper, we researched the optical properties of asymmetric transmission devices for onedimensional functions photonic crystals. The refractive indices of media A and B are not constant, it is the functions of space coordinate. By calculated the transmissivity and electric field distribution of asymmetric transmission devices, we found that when the forward incident light can transmit the function photonic crystals, but the backward incident light did not transmit through it, the function photonic crystals can be made into asymmetric transmission devices. Such as optical diodes or optical triode, etc.
