Paper Abstract

This paper presents an IIR (infinite impulse response) structure for an optical interleaver to deliver simultaneously three channels of 2π/3 shifted passband transmissions. Using the proposed structure, the phase responses and the spectral response of the IIR interleaver can be designed separately. Therefore, the design of an IIR interleaver is simplified, and the obtained interleaver can achieve a better performance than that of an FIR (finite impulse response) interleaver in terms of wider passband bandwidth, higher channel isolation, and lower insertion loss. A numerical design example is given to demonstrate the effectiveness of the proposed IIR interleaver design scheme.
