ABSTRACT
An integrated flexible-grid 1×2 wavelength-selective switch based on reconfigurable add-drop silicon microring resonators using strip waveguides is designed and experimentally demonstrated. By flexibly tuning the resonance of microring resonators and path phase differences via the thermo-optic effect, the transmission spectra with adjustable bandwidths can be formed as desired at the output ports. Our experimental results reveal that the fabricated flexible-grid 1×2 wavelength-selective switch provides crosstalk lower than -10.39 dB. The 3-dB bandwidth varies from 0.38 nm to 1 nm, the in-band ripple is less than 0.52 dB, and the response time is about 17.6 µs.
