Paper Abstract

One-dimensional photonic crystals with periodic structure have been limited to only one direction in space and have been around for quite a long time in the very fertile field of thin film optics. Our periodic many-layered thin film (1-D Photonic Crystal) model consists of two types of layered medium in which one layer has gain. The optical properties of transmission and reflection are studied in this 1-D Photonic Crystal with gain. The relationship of transmission coefficient with wavelength, gain and the thickness of media, and the relational expression of critical length with gain are all obtained by using the transfer-matrix method. The mode of divergence points of transmission coefficient depend on the gain, thickness and thickness of monolayer media are analyzed, and it is compared with the Fabry-Perot (F-P) system. It is found that the gain suppress the transmission and the media will be equivalent to a reflector when the gain is large. These simulated calculations are valuable in the design of optical device based on photonic crystal.
