Paper Abstract

Dual Band Wavelength Demultiplexer (DBWD) is designed to separate two telecommunication wavelengths, 1.31μm and 1.55 μm utilizing photonic crystals (PhC) in Silicon on Insulator (SOI). The waveguides formed in such PhC structures confine light horizontally by a photonic bandgap and vertically by total internal reflection. Plane Wave Expansion (PWE) method and Finite Difference Time Domain method are used to design and analyze the DBWD in Y type PhC. Numerical analysis indicates that the separation of two wavelengths with enhanced extinction ratio, transmittance and quality factor can be achieved, which confirms the superior performance of the proposed design of DBWD
