Abstract

Modelling of quadruple asymmetrical micro optical ring resonator is carried out in this paper and its performance as optical filter is analysed. Unit delay signal processing technique is implemented to model the proposed the proposed configuration in z-domain. MATLAB software is used to determine the free spectral range (FSR), group delay and dispersion characteristic of proposed configuration. Coupler design of the proposed configuration is done using Finite Difference Time Domain (FDTD) method.
