    Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for a photonics integrated circuit (IC) for an optical neural network (ONN). In embodiments, the photonics IC includes monolithically optoelectronic components in a single semiconductor substrate including a combination of one or more of integrated array of light sources, a plurality of optical modulators, an optical unitary matrix multiplier, non-linear optical amplifiers or attenuators, and a plurality of photodetectors. In embodiments, the optical unitary matrix multiplier comprises a plurality of 2×2 unitary optical matrices optically interconnected, wherein each 2×2 unitary optical matrix comprises a plurality of phase shifters. In embodiments, each 2×2 unitary optical matrix is to phase shift, split, and/or combine one or more of the optical signal inputs. Other embodiments may be described and/or claimed.

    Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical accelerator including a photonics integrated circuit (PIC) for an optical neural network (ONN). In embodiments, an optical accelerator package includes the PIC and an electronics integrated circuit (EIC) that is heterogeneously integrated into the optical accelerator package to proximally provide pre- and post-processing of optical signal inputs and optical signal outputs provided to and received from an optical matrix multiplier of the PIC. In some embodiments, the EIC is a single EIC or discrete EICs to provide pre- and post-processing of the optical signal inputs and optical signal outputs including optical to electrical and electrical to optical transduction. Other embodiments may be described and/or claimed.

    Abstract: Embodiments may relate to a segment driver that is to be coupled with a modulator segment of a Mach-Zehnder modulator. The segment driver may include a continuous-time linear equalizer (CTLE) incorporated within an amplifier stage of the modulator. The CTLE may be configured to identify an electrical signal that is related to an optical signal of the Mach-Zehnder modulator; reduce inter-symbol interference (ISI) of the electrical signal to generate a processed electrical signal; and output the processed electrical signal to the amplifier stage. Other embodiments may be described or claimed.
