Research Topics:  Microstructure Fiber for Optical Communications and Medical Applications

 

Abstract

We propose a simple highly nonlinear photonic crystal fiber for generating supercontinuum (SC) spectrum in telecommunication window. Based on the finite difference method, different properties of highly nonlinear photonic crystal fibers are calculated. It is demonstrated that the nonlinear coefficients more than 113 [Wkm]−1 at 1.0 μm, 71 [Wkm]−1 at 1.30 μm and 51 [Wkm]−1 at 1.55 μm with flattened chromatic dispersion and low confinement losses simultaneously.  Moreover, it is shown that it is possible to generate wide SC spectrum using 1.0 ps input pulses to achieve longitudinal resolution of 1.5 μm and 1.1 μm at 1.06 μm and 1.31 μm center wavelengths, respectively.

 

 

Research Topic:  Designing Dispersion Compensating Microstructure Optical Fiber

 

Abstract

We design a hexagonal model of dispersion compensating photonic crystal fiber using finite element method with perfectly matched layer as an analysis tool. In this case, we change different parameters-diameter of air holes and pitch to observe the effects of different properties of dispersion compensating photonic crystal fiber such as effective area, confinement loss and chromatic dispersion. We have achieved large negative chromatic dispersion, and low confinement loss. Moreover, numerical results show that small length of the proposed dispersion compensating photonic crystal fiber is achieved. The proposed microstructure fiber can be used for wide band high speed optical transmission systems.
