光子晶体是由介电常数不同的材料周期性分布而成，可以用来控制光的传输。
Photonic crystals are the periodical arrays of materials with the different refractive indices which can control the light propagation.
光子材料由介电常数高低不同的材料交替排列组成—这种纳米结构会影响该种材料中光的通过。
Photonic materials are made up of alternating regions of high and low dielectric constant - a nanostructure that affects the flow of light through the material.
