PCF Structure with Circular Air Hole and Square Lattice and its High Birefringence and Lower Zero Dispersion Behavior

Pranaw Kumar; Abhijit Mishra

In this paper a square lattice Photonic Crystal Fiber (PCF) with circular air hole has been designed and the numerical analysis reported a zero dispersion for one of the proposed structure. A very high Birefringence of the order of have been observed. Among all the structures proposed, two structures have shown both increment and decline in the value of confinement loss at the same interval of wavelength. It has also been shown the shifting of zero of dispersion wavelength toward lower wavelength range with increase in the number of circular air holes of large area compared to the number of circular air holes of smaller area. A Full- vector TM, FDTD method has been used.
