摘要
In this paper, a novel tellurite glass based hybrid-core photonic crystal fiber (HCPCF) with large birefringence and high nonlinearity is designed. The optical characteristics including the birefringence, nonlinearity, and group-velocity dispersion are studied by using full-vector finite element method. Simulation results show that large birefringence of 0.119 and high nonlinear coefficient of 3.42 W−1/m around 1550 nm can be obtained simultaneously, and the dispersion parameter can be flexibly adjusted. The HCPCF designed can find significant applications in optical communication, signal processing, and sensing systems.
