光子晶体制备方法最新进展

Recent progress in the fabrication of photonic crystals

光子晶体是一种介电常数随空间呈周期性变化的材料。具有光子带隙结构(Phtotonic Band Gap)的光子晶体,可以调制光子的状态模式,其潜在用途十分广泛。本文介绍了光子晶体的制备方法及其进展。

Photonic crystals have emerged as a new kind of microstructure materials whose dielectric constant changes alternately following the coordinates of space. Analogous to the normal atomic crystals, photonic crystals with 'photonic bandgap' can modulate the modes of electromagnetic waves in much the same way that semiconductors control the properties of electrons. There are a lot of methods to fabricate photonic crystals. Here in the recent progress for preparation of photonic crystals is reviewed.
