摘要: We have proposed and demonstrated the basic elements of a full matrix optical switching circuit (cross-connect circuit) using hitless wavelength selective switch (WSS). The cross-connect circuits are made multi-wavelength channel consisting cascaded WSSs, multi-port switch. These realized through individual Thermo-Optic (TO) tuning series-coupled microring resonator, can arbitrary channels without blocking other during tuning. demonstrate four wave-length parallel topology double series coupled resonators three quadruple resonators. Since spectrum shape is much more box-like than series, high extinction ratio 39.0–46.6 dB low witching cross talk 19.3–24.5 were achieved.
