Photonic crystal fibers (PCF) sensors have broad application in the pressure environmental monitoring.The birefringence of the dual-hole core photonic crystal fibers is analysed by the full-vect finite element methods, the photonic crystal fibers sensors response to pressure is simulated by the second-order differential equation theoretical model and the influence to the effective refractive index and the birefringence of the sensing element are discussed by the model, the high-pressure photonic crystal fibers sensors scheme is presented. Calculation results show that the birefringence of the dual-hole core photonic crystal fibers is very large. The system of the pressure photonic crystal fibers sensors is brevity and compaction.
