摘要
研究了材料和基底的吸收对二维光子晶体的影响,采用传输矩阵法沿某一晶格方向对光子晶体进行分层,然后基于各层传输矩阵求解能带结构。研究发现,吸收使原来不存在带隙的频率上出现新带隙,而原有带隙则得到拓展,其中TE 波受吸收的影响比TM 波大.
Abstract
The influence of the two dimensional photonic crystals on the absorption of materials and the substrate is studied. By using the transfer matrix method along with a certain direction of lattice photonic crystal, the energy band structure based on the transfer matrix method is solved. Researches show that absorption can bring new band gap to a frequency which doesn′t have band gaps, while extending the range of the original band gap, and TE wave is more impacted than TM wave by the absorption.
