Abstract
A carrier-effect based optical switch, a method of operating the carrier-effect based switch, and a controller module for controlling a carrier-effect based optical switch are provided. 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.
