Summary:
We demonstrated a multi-wavelength channel selective switch using individual Thermo-Optic tuning of quadruple series-coupled microring resonators. The extinction ratio and the switching crosstalk were extremely improved to 51.8dB and -23.9dB, respectively, from those of double series-coupled device (27.2dB and -8.4dB).
