Tunable Germanium-on-Insulator Band-Stop Optical Filter Using Thermo-Optic Effect

Tunable Germanium-on-Insulator Band-Stop Optical Filter Using Thermo-Optic Effect

We demonstrate a tunable band-stop optical filter on a germanium-on-insulator photonic platform operating at 1.95 <italic>&#x03BC;</italic>m wavelength. The band-stop filter is implemented using parallel-coupled microring resonators with the number of microring resonators varied from...
