An interleaver design based on the phase characteristics of Gires-Tournois resonator

摘要

Two interleavers with potential applications for dense wavelength division multiplexing (DWDM) system are designed based on the analysis of the phase characteristic of Gires-Tournois resonator. One has only one G-T resonator and the other has two. The performance of the two interleavers has been compared .We find the latter is better than the former and an Interleaver of a channel spacing of 50GHz, ripple less than 0.05dB, a -0.5dB passband of 23.4GHz (46.8% of the spacing), a-30dB stopband of 20.8GHz (41.6% of the spacing), and a channel isolation of -33.95dB is obtained.
