非线性光子晶格的制作及光传输现象研究

Study on the fabrication of nonlinear photonic lattice and its light-guidance effects

采用数值和实验方法研究了非线性光子晶格图样的形成规律及光传输现象。采用光束传输法(BPM)模拟研究光波在由干涉图样及非线性作用下形成的光子晶格中的导光现象。通过多光束干涉观察了干涉图样,并由此制作了光子晶格。研究结果为利用非线性效应制作周期性光子晶格和准周期性光子晶格,并以此实现导光功能提供了新的思路和方法。

The study numerically and experimentally discussed the fabrication of nonlinear photonic lat -tice and the light-guidance in photonic lattices .The light interference patterns and the light propagation dynam-ics were both simulated with Matlab using Beam Propagation Method .Experimental observation was used to get the interference patterns and the photonic lattice .The study may provide a way to the fabrication of periodic and quasi-periodic photonic lattices and the light guidance in such structures .
