    Abstract: In example implementations, a method executed by a processor is provided. The method receives a simulated photonic data input based on a theoretical photonic design that meets a target specification. A complementary metal-oxide semiconductor (CMOS) circuit design is designed based on the simulated photonic data input using a pre-layout simulation. An experimental photonic data input based on a fabricated photonics device that meets the target specification is received. The CMOS circuit is designed based on the experimental photonic data input using a post-layout simulation. A physical circuit CMOS circuit design and a layout that includes detailed physical dimensions associated with the physical CMOS circuit design that is based on the pre-layout and the post-layout are transmitted to a CMOS foundry.

    Abstract: Examples described herein relate to concurrently performing operations on optical signals. In an example, a method includes providing, to an optical circuit, a first plurality of signals having a first optical property and encoding a first vector. A second plurality of signals is provided to the circuit that encodes a second vector and has a second optical property that is different from the first optical property. A first attribute-dependent operation is performed on the first plurality of signals via the circuit to perform a first matrix multiplication operation on the first vector, and concurrently, a second attribute-dependent operation is performed on the second plurality of signals to perform a second matrix multiplication operation on the second vector. The first matrix multiplication operation and the second matrix multiplication operation are different based on the first optical property being different from the second optical property.

    Abstract: An optical system includes an output waveguide to propagate an optical output signal and a plurality of ring laser systems. Each of the plurality of ring laser systems includes a ring laser to generate a ring laser optical signal and a local waveguide. The ring laser can be optically coupled to the output waveguide to provide a first portion of the ring laser optical signal on the output waveguide as part of the optical output signal, and can be optically coupled to the local waveguide to provide a second portion of the ring laser optical signal on the local waveguide. Each of the plurality of ring laser systems can be to control a phase of the second portion of the ring laser optical signal to provide constructive interference with the ring laser optical signal at an optical coupling of the ring laser and the local waveguide.

    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 disclosed herein relate to quantum-dot (QD) photonics. In accordance with some of the examples disclosed herein, a QD semiconductor optical amplifier (SOA) may include a silicon substrate and a QD layer above the silicon substrate. The QD layer may include an active gain region to amplify a lasing mode received from an optical signal generator. The QD layer may have a gain recovery time such that the active gain region amplifies the received lasing mode without pattern effects. A waveguide may be included in an upper silicon layer of the silicon substrate. The waveguide may include a mode converter to facilitate optical coupling of the received lasing mode between the QD layer and the waveguide.
