Design and analysis on a Gires-Tournois resonator based interleaver

Abstract

A flat-top interleaver, in which a mirror on one arm of the Michelson interferomefer is replaced by a G-T resonator, is proposed. In the interleaver, the parameters including the channel spacing of 50 GHz, ripple less than 0.05 dB, −0.5 dB passband of 43 GHz (86% of the spacing), −30 dB stopband of 42 GHz (84% of the spacing), and a channel isolation higher than 40 dB, are achieved.
