二维光子晶体能够实现光子晶体的多种特性要求,能采用传统波导理沦实现功能器件,因而受到极大的关注和广泛的应用。全息光刻是一种利用两束或多束空间和时间相干性都很好的激光光束从不同方向照射同一位置而产生驻波,从而制备周期性微纳米结构的激光微加工技术。为了制备特殊基底(如新型功能纳米复合材料)的微纳米周期性结构,
Two-dimensional photonic crystals can meet the various requirements of photonic crystals and can be realized by traditional waveguides. Therefore, the two-dimensional photonic crystals are greatly concerned and widely used. Holographic lithography is a kind of laser micromachining technology that uses two or more laser beams with good spatial and temporal coherence to irradiate the same position from different directions to generate standing waves to prepare periodic micro and nano structures. In order to prepare the micro-nano periodic structure of a special substrate (such as a novel functional nano-composite)
