    Abstract

    A compact [200 x 200 μm^2] wavelength-selective switch based on thermally tunable SiO2-Si3N4 microring resonators has been designed and realized. The switch supports gigabit filtering applications in access networks. Spectral measurements show an ON-OFF ratio of 12 dB and a channel separation of 20 dB. The 10-Gb/s measurements on a single ring show no degradation of the modulated signal and a theoretical BER (bit-error rate)<10^-12.
