Design of Non-reciprocity Layered One-dimensional Photonic Crystal Structure

Abstract Photonic crystal is a dielectric structure,whose refractive index varies periodically in space,namely the photonic band gap material.The fundamental properties of photonic crystals are photon localization and the photonic band gap.In addition,there are many new physical phenomena,such as super-prism effect of light,energy transfer,optical bi-stability and so on.With photonic crystals appearing,the dream of manipulating and controlling the photonic becomes possible..In recent years,with the development of new laser technology,computer,information,optical fiber communication,research and application of the magneto-optical effects continue to develop the depth and breadth,and the emergence of many new magnetic materials and magnetic optical devices.From the study of magneto optical materials and devices into an unprecedented period of development,and has been widely used in many high-tech fields,and all kinds of magneto optical materials and devices also demonstrated its unique properties and wide application prospect,and has aroused strong interest.
In this paper,through theoretical analysis and numerical simulation,we studied some properties of non reciprocity layered one-dimensional photonic crystals.Firstly,the concept with properties and applications of photonic crystal are briefly discussed.And then, we demonstrated some important properties of crystals by theory.At the same time,characteristic and the theory of magneto optic crustal are introduced simply.Secondly,we paved the way about studying nonreciprocal layered one-dimensional photonic crystal.The theory includes the photonic band gap of one-dimensional photonic crystal, photonic localization characteristics, transmission characteristics and the transmission matrix, and magneto optical material of magneto optical Faraday effect, Kerr effect etc.Finally,through theoretical analysis and numerical simulation,design a non reciprocal layered one-dimensional photonic crystals.

Key words One-dimensional photonic crystal Photonic band gap Magneto optical materials Magnetic photonic crystals Magneto optical effect Non reciprocal
