This paper presents an infinite impulse response (IIR) structure for designing a three-port optical interleaver. With the proposed IIR structure, the spectral responses of the interleaver can be designed in two steps to achieve simultaneously three channels of identical but 2π/3 shifted passband transmissions. Compared with a three-port finite impulse response (FIR) interleaver, the proposed IIR interleaver is superior in several aspects: it uses only two 3×3 couplers, it provides a better form factor and has an improved side-lobe suppression. Simulation results are given to demonstrate the effectiveness of the proposed IIR interleaver design scheme.
