Photonic microwave filtering using coherently coupled integrated ring resonators Academic Article uri icon


  • Filtering of microwave signals using coupled photonic ring resonators fabricated in the silica waveguide technology is described. Integrated thermo-optic phase shifters allow for control of the optical phase and the passband shape. Tuning of the microwave passband via optical wavelength and phase is demonstrated.
