A Kind of Hollow Dual-Core Photonic Crystal Fiber with Zero Inter-Modal Dispersion
A hollow dual-core photonic crystal fiber (HC-PCF) filled with high refractive index liquid sensitive to temperature is analyzed. The coupling properties and the inter-model dispersion are investigated by using full-vector finite element method (FEM). Theoretical results show that with the increase of the wavelength, the coupling coefficient will decrease first and then increase for a certain temperature. Especially, the zero inter-modal dispersion can be achieved at a particular wavelength. By adjusting the temperature and/or the structure parameter d/Λ, zero inter-modal dispersion in an extremely wide wavelength range including both 1.31 μm and 1.55 μm is realized. This implies that the pulse distortion effect due to the mismatch between different modes can be eradicated and 100% power transfer can be realized in such a hollow dual-core photonic crystal fiber.
