  A method of optical microwave generation based on high birefringence photonic crystal fiber (PCF) is proposed. To design a high birefringence of PCF, a full vector finite element method is used. Theoretical analysis and results show that the microwave signal frequency is proportional to the birefringence in a certain range with the continuous pulse laser injection. When the birefringence is the odd times of 1.94 ×10-4, microwave frequency can reach a maximum value 25.91 GHz. The simulation results demonstrate the feasibility of optical microwave generation using high birefringence photonic crystal fiber.
