摘要
利用光束传播法对带隙型光子晶体光纤(photonic crystal fiber,PCF)的泄露谱进行了数值分析.结果表明:PCF泄露谱往往具有多个带隙;泄露谱对PCF结构的变化异常敏感,泄露峰值波长和带隙波长不但与空气孔周期有关,还受空气孔直径的影响;由于PCF的空气孔内可填充液晶,泄露特性对液晶折射率的变化极其敏感,当液晶折射率增大时,峰值泄露波长和带隙波长都向长波漂移.
Abstract
The leaky spectrum of Photonic crystal fibers (PCF) was simulated with beam propagation method. The results showed that the leaky spectrum usually had several bandgaps,which would provide theoretical reference for designing a novel multi-band filter. Furthermore,the leaky spectrum was very sensitive to the PCF structure,the spectrum was affected not only by the period of the air hole but also by its dimension. Finally,the liquid crystal (LC) could be infiltrated in the air holes of the PCF,because the refractive index of LC could be tuned by controlling the voltage and the temperature. The peak leaky wavelength and bandgap wavelength would red shift with the LC refractive index increasing,which would provide reference for designing a novel tunable filter and optical switch by controlling the voltage or tune the LC temperature.
