Objectives: Bending insensitive Photonic Crystal Fiber will possess low loss and the research aims for high birefringence and large nonlinearity. Bending insensitive Photonic Crystal Fiber (PCF) along with high birefringence and high nonlinearity is being presented in this paper. Methodology: The fiber is bent by applying some bending radius along with the angle in the direction of the bending and the effects due to these angles are being extensively studied by using Finite Element Method (FEM). Findings: The birefringence in the range of 10-2 can be achieved and nonlinear coefficient in the range of 70-110 W-1Km-1 can be obtained. The PCF possesses very low effective mode field area (MFA) which would be leading to positive effect on the bending losses. The number of air hole rings used in the designed structure is very less so the designed fiber is easy to fabricate. Applications: This fiber can be used in the medical applications for detecting the tumors, for Optical Code Division Multiple Access (OCDMA) applications, high power laser applications.
