Abstract

A high birefringence Photonic Crystal Fiber（PCF） with a new structure for pressure sensing is presented.With the external lateral pressure

the effective refractive indexes of its two polarization states change and its birefringence alters accordingly.Pressure sensing is achieved by measuring the variations of the polarization state brought about by that of birefringence.Simulation results show that the birefringence PCF changes significantly under the lateral pressure

to the extent of as 0.7×10-5/MPa.
