摘　　要：文章提出一种利用硅树脂调节光子晶体光子带隙的方法,光子晶体波导是通过往二维正方形光子晶体的介质柱之间填充硅树脂得到的,利用温度场改变硅树脂的折射率。数值模拟结果表明:通过温度场可对这种光子晶体的禁带结构进行调节。这种可调光子晶体可应用于制作新颖的偏光片和光开关。In this paper, we report a novel method for the control of the photonic band gap of photonic crystals （PC）. PC waveguides can be obtained by infiltrating silicon resin into the air regions in 2D photonic crystals composed of square lattices of dielectric cylinders. The refractive indices of silicon resin can be changed by temperature. Numerical simulation results show that the band gaps of the photonic crystal can be tuned by temperature manipulation, which can be used for making novel optical switches and field-sensitive polarizers in photonic integrated circuits.
