Abstract

A signal interleaver/ deinterleaver based on ring resonators is proposed and analyzed with the transfer matrix and the Z-transform techniques. The proposed structure is composed of rings connected in a closed loop and is termed a “compound ring resonator circuit.” The interleaver/deinterleaver circuit is designed to meet wavelength division multiplexing (WDM) specifications for two channels of spacing of 50 GHz , a channel free spectral range of 100 GHz , a crosstalk of 24 dB , and a maximum dispersion of ± 22 ps nm over a ± 10 GHz bandwidth at a wavelength of 1.55 μ m . Compared with previous circuits of this nature, this circuit possesses a smaller number of rings, a simpler design, does not require apodization, exhibits less dispersion, and offers a higher fabrication tolerance and density.
