Abstract
Provided is a device for modulating or switching an optical signal, comprising a first ring waveguide made of a first material with at least one p-n or p-i-n junction, and a second ring waveguide arranged axially opposite the first ring waveguide. The second ring waveguide is made of a second material that has a thermo-optic coefficient lower than the thermo-optic coefficient of the first material. The first ring waveguide is a sub-wavelength network.
