The carrier-effect based optical switch comprises input and output optical couplers, first and second optical waveguide arms each connecting the input optical coupler to the output optical coupler, a first junction diode proximate to the first optical waveguide arm for providing a first optical phase delay thereto due to at least a carrier-based effect, and a first resistive heater proximate to the second optical waveguide arm for providing a second optical phase delay thereto due to a thermo-optic effect. The method comprises applying a first electrical power to the first junction diode for providing a first optical phase delay thereto due to at least a carrier-based effect, and applying a second electrical power to the first resistive heater for providing a second optical phase delay thereto due to at least a carrier-based effect. The controller module comprises code which, when executed on a computing device, causes the controller module to perform the method.

摘要： An aspect of the disclosure provides a microring resonator (MRR). Such an MRR includes a ring optical waveguide and an optical waveguide, with the optical waveguide configured such that a first portion of the optical waveguide overlaps a second portion of the ring waveguide. In some embodiments, the optical waveguide has a first refractive index and the ring optical waveguide has a second refractive index such that the first refractive index is less than the second refractive index. In some embodiments, the optical waveguide is a polymer optical waveguide and the ring optical waveguide is a silicon optical waveguide. In some embodiments, the optical waveguide is larger in height than the ring waveguide and the first portion of the optical waveguide is configured to provide space for the second portion of the ring waveguide.
