Abstract
This paper describes two kinds of circuit configuration to design interleaver, which are implemented by a single stage M-Z interferometer whose two arms are connected with ring waveguides. When the two configurations circuits are composed of M rings and N rings, respectively, (2M+2N+1)th-order interleaver characteristics can be realized. For two kinds of structure, design examples including third-order interleaver and fifth-order interleaver and seven-order interleaver are demonstrated. By theoretical analysis of the transmission function, The power transmittances spectrums are calculated, the circuit parameters are gained. Compared the power transmittances spectrums among third-order interleaver, fifth-order interleaver and seventh-order interleaver, it is found that with order of interleaver added, flat-top effect is better, the steeper spectral responses of the stopband and passband are achieved, and power transmittances get closer to square wave.
