摘　　要：A novel attempt has been made in this paper for a different approach for determination of ring resonator transmittance with the help of delay line signal processing techniques and Totally Coded Method(TCM).A generalized approach for determination of transfer function in Z-domain of optical waveguide based ring resonator is introduced.Delay line signal processing technique is used to develop the signal flow graph of different ring resonator architectures,and a rule is implemented to determine its overall transmittance.The parameters describing the performance of optical filter can be directly estimated from the frequency response plot.A waveguide based double ring resonator(DRR) architecture is proposed,and its frequency response analysis is carried out.A novel attempt has been made in this paper for a different approach for determination of ring resonator transmittance with the help of delay line signal processing techniques and Totally Coded Method （ TCM ）. A generalized approach for determination of transfer function in Z-domain of optical waveguide based ring resonator is introduced. Delay line signal processing technique is used to develop the signal flow graph of different ring resonator architectures, and a rule is implemented to determine its overall transmittance. The parameters describing the performance of optical filter can be directly estimated from the frequency response plot. A waveguide based double ring resonator（DRR） architecture is proposed, and its frequency response analysis is carried out.
