摘　　要：提出一种可填充E7型液晶的不同孔形光子晶体光纤。基于现有Comsol Muhiphysics软件对不同温度时的光子晶体光纤在同一波长传输特性的影响,从而实现温度变化对填充液晶的不同孔形光子晶体光纤的模场特性规律,得出基膜有效折射率、数值孔径随温度变化快的圆形空气孔是表现光子晶体光纤传输特性的最佳孔形。分析波导色散随入射波长变化的影响,为更好地调制光子晶体光纤器件提供理论依据。A different hole-shaped photonic crystal fiber filled with E7 liquid crystal is proposed, based on the influence of Comsol Muhiphysics software on the transmission characteristics at the same wavelength of the photonic crystal fiber at different temperatures, the rule of temperature change impact on the mode field characteristics of different hole-shaped photonic crystal fi- ber filled with liquid crystal was achieved. The result is that the circular air hole is the preferred hole shape for transmission characteristics of the photonic crystal fiber, whose effective refractive index of fundamental mode and the numerical aperture change is fast with temperature changes. The influence of waveguide dispersion variation with the incident wavelength is ana- lyzed. A theoretical basis was provided for better modulation of photonic crystal fiber devices.
