Designing photonic crystal fiber for optical sensor and medical application and suitable for wavelength division multiplexing systems

摘要

Simulation results of a Photonic crystal fibers (PCFs) structure with two elliptical holes and circular holes have been studied. Area of elliptical holes are sixteen times more than that of circular holes. The simulation results shows that designed fiber can have wide application in various linear and nonlinear applications. The birefringence reported is very high and is of the order of 10-2. Dispersion observed at all the four optical windows is very low. However the reported dispersion is below 20psm - km. Thus designed fibers can be used for optical sensor, optical switching and broadband amplification and other nonlinear properties. Besides we have studied confinement loss and normalized frequency of the designed fiber.
