An Algorithm for Reconfigurable Coupled Resonator Optical Waveguides

Abstract

We have developed an algorithm for (re)configuration of Coupled Resonator Optical Waveguides filters. We analyze in detail the effect of the phase shift introduced by tunable Mach-Zehnder interferometers. An alternating pattern is proposed to drive every other tunable coupler. We verified this algorithm to realize a user-defined all-pole filter function in circuit simulation.
