| Popis: | We fabricated a wavelength-selective switch composed of microring resonators as wavelength filters and Mach–Zehnder-interferometer-based thermo-optic switches as routing switches. Nonblocking wavelength-selective switching operations for several channels were successfully demonstrated. A wavelength-selective transmittance change of 9.7 dB was obtained at a wavelength channel of 1548 nm, which is one of four wavelength channels in a wavelength range between 1535 and 1570 nm. An electric power of 17.9 mW was applied for switching the thermo-optic switch from a cross state to a bar state. The change in transmittance in other wavelength channels is |
