    Abstract: Waveguide shuffle blocks (WSBs) are provided that may incorporate waveguides routed in any pattern to effectuate many-to-many connectivity between optical cables/fibers or other WSBs connected thereto. Such WSBs may be configured in ways that allow the WSBs to be stacked and to achieve effective optical cable/fiber organization. Moreover, such WSBs may include readable tags that can provide information regarding a particular WSB configuration and/or what optical cables/fibers are connected so that network topology can be discovered and monitored. Some WSBs may be configured as wavelength shifting shuffles (WSSs) that allow a particular wavelength(s) of an optical signal(s) to be routed as desired and/or alter a first wavelength associated with a particular optical signal to a second wavelength. In other embodiments WSSs can be configured to allow for wavelength multiplexing/demultiplexing.

    Abstract: Example optical devices having a Mach-Zehnder interferometer (MZI) with improved linearity are presented. An example optical device may include an MZI and a microring resonator (MRR) optically coupled to any one of a first optical waveguide arm or a second optical waveguide arm, where the MRR is operable in a resonance state and in an off-resonance state during operation of the optical device. The MZI includes a length difference between the first optical waveguide arm and the second optical waveguide arm thereby achieving a quarter-period phase delay between optical signals of the first optical waveguide arm and the second optical waveguide arm such that a superlinear transmission region of the microring resonator is aligned with peaks of an optical output of the MZI improving linearity of the optical output of the MZI.

    Abstract: Implementations disclosed herein provide for devices and methods for obtaining parity time (PT) symmetric directional couplers through improved phase tuning, along with separate optical gain and optical loss tuning. The present disclosure integrates phase tuning and optical gain/loss tuning structures into waveguides of directional couplers disclosed herein. In some examples, directional couplers disclosed herein integrate one or more hybrid metal-oxide-semiconductor capacitors (MOSCAPs) formed by a dielectric layer between two semiconductor layers that provide for phase tuning via plasma dispersion and/or carrier accumulation depending on voltage bias polarity, and one or more optically active medium that provide for optical gain or loss tuning depending on voltage bias polarity.

    Abstract: Examples described herein relate to an optical coupler. The optical coupler may include a first optical waveguide base layer, a second optical waveguide base layer, an insulating layer disposed over at least a portion of both the first optical waveguide base layer and the second optical waveguide base layer, and a semiconductor material layer disposed over the insulating layer. Overlapping portions of the first optical waveguide base layer, the insulating layer, and the semiconductor material layer form a first optical waveguide, and overlapping portions of the second optical waveguide base layer, the insulating layer, and the semiconductor material layer form a second optical waveguide. Moreover, the optical coupler may include a plurality of metal contacts to receive one or more first biasing voltages to operate one of the first optical waveguide base layer and the second optical waveguide base layer in an accumulation mode.

    Abstract: Systems and methods are provided for devices and methods for implementing an optical neural network (ONN) by leveraging resonator structures, such on micro-ring resonators (MRRs). Examples include unit cells configured to perform a linear transformation on optical signals. Each unit cell comprises a plurality of signal mixing components optically coupled to between adjacent waveguides, where each signal mixing component corresponds to a distinct wavelength and is configured to mix optical signals on the adjacent waveguides at the distinct wavelength. Each unit cell also includes a plurality of phase tuning components each corresponding to a distinct wavelength and configured to adjust a phase of a mixed optical signal at the distinct wavelength.
