Analytical studies on FBG based SOI structure for realization of optical interconnect

Abstract

In this research, fiber based BiFeO3-air structure is lucidly investigated at wavelength of 1.55 μm for optimization of reflectance, diffraction and dispersion loss in order to maximize the transmitted efficiency. Here bismuth ferrite (BiFeO3) is taken as odd layer and air is taken as even layer to realize the SOI waveguide fiber brag structure. Further plane wave expansion (PWE) technique is deployed for simulation of reflectance, whereas diffraction efficiency and dispersion efficiency is simulated through simple numerical formulations. However, numerous structure parameters such as refractive indices and thickness of odd and even layer along with number of fiber bragg layer plays key role to envisage high transmitted efficiency in the proposed structure. Simulation outcomes divulged that very high transmitted intensity is achieved, hence the proposed fiber brag structure can be regarded as a promising candidate as optical interconnect for photonic integrated circuit.
