Design and Analysis of Spiral Photonic Crystal Fiber for Ultra-Flattened Dispersion for C+L+U
A design of two-dimensional photonic crystal fiber with circular air hole, and it analyzes for large fattened dispersion for diameter 0.6 um in the wavelength range 1.55–1.78 µm. A step-by-step design optimization is demonstrated and maximum optimized value of total dispersion for diameter of 0.6 µm at 1.25 µm is 3.65 ps/nm.km. The PCF has spiral layout. There are five rings around the air core. Three layouts of spiral PCF are designed for different diameter of air hole and compared with layout having decagonal structure using finite element method. The optimized design can be used as dispersion control and as well as dispersion shifted photonic crystal fiber.
