ABSTRACT
Micro-Ring Resonators (MRRs) have great interest due to different applications especially in secured communication and light storage in optical buffers. This chapter provides the Vernier operation with Signal Flow Graph (SFG) which is a graphical approach for analyzing the intricate photonic circuits mathematically and quick calculation of optical transfer function. It analyses a Cascaded Micro-Ring Resonators (CMRR) made of InGaAsP/InP semiconductor using the SFG method which enables modelling the transfer function of the passive CMRR. The chaotic behavior of the multi output signals can be filtered using appropriate parameters of the add/drop filter system. Therefore the output signals are free from chaotic signals where multi soliton wavelength can be used to increase the capacity of the communication network link. There are a number of important characteristics of the ring resonator which include the Free Spectral Range, Full Width at Half Maximum, and Finesse and Quality factor.
