Abstract: A photonic integrated circuit is provided that is adapted to compensate for an unintentional manufactured refractive index profile, such as a gradient, that arises due to manufacturing variance. The photonic integrated circuit including at least a thermal source and a spaced thermal sink to induce a thermal gradient in the photonic integrated circuit between the thermal source and the spaced thermal sink, the thermal gradient imparts an opposing thermal refractive index profile to correct for the manufactured refractive index profile. In some embodiments the photonic integrated circuit may be constructed with features that have an intentional structured refractive index profile that ensures any unintentional manufactured refractive index profile is correctable by the opposing thermal refractive index profile induced by the thermal source.

Abstract: An optical transmitter including an optical waveguide and N microring resonators (MRRs) coupled to the optical waveguide is provided. In such an optical transmitter each of the N MRRs having a different coupling coefficient determining the amount of coupling to the optical waveguide, wherein N>1. In some embodiments, each of the N MRRs has a different spacing distance from the optical waveguide, wherein the coupling coefficient for each MRR is dependent on the spacing. In some embodiments the optical transmitter further includes an input for receiving N drive signals from a controller, each drive signal shifting the resonant wavelength of the corresponding MRR to control the optical power coupled in the corresponding MRR from the optical waveguide in which an optical signal propagates.

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.

Abstract: An optical attenuator and/or optical terminator is provided. The device includes an optical channel having two regions with different optical properties, such as an undoped silicon region which is less optically absorptive and a doped silicon region which is more optically absorptive. Other materials may also be used. A facet at the interface between the two regions is oriented at a non-perpendicular angle relative to a longitudinal axis of the channel. The angle can be configured to mitigate back reflection. Multiple facets may be included between different pairs of regions. The device may further include curved and/or tapers to further facilitate attenuation and/or optical termination.
