Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for optical couplers comprising a first optical waveguide and a second optical waveguide coupled to form a 2×2 optical unitary matrix to receive a respective first input optical signal and a second input optical signal. In embodiments the first optical waveguide and second optical waveguide form arms that converge alongside each other to direct the first input optical signal and the second input optical signal along a path that integrates a plurality of tunable phase shifters to transform the first input optical signal or the second input optical signal into a first output optical signal and second output optical signal to be output from the 2×2 optical unitary matrix. Additional embodiments may be described and claimed.

Abstract: Some embodiments of the present disclosure describe an apparatus for III/V-Si taper coupling, including a III/V-Si taper coupler with one end to receive a laser beam where the one end has at least one surface at a non-perpendicular angle with respect to a direction of the laser beam, and where the at least one surface forms one or more tips at the one end of the III/V-Si taper coupler. The one end is positioned so that the one or more tips are outside the laser beam to reduce reflection of laser beam away from the one end of the III/V-Si taper coupler.

Abstract: Embodiments of the present disclosure are directed toward techniques and apparatus comprising at least one layer of an ONN that includes an optical matrix multiplier provided in a semiconductor substrate to receive a plurality of optical signal inputs and to linearly transform the plurality of optical signal inputs into a plurality of optical signal outputs. The optical matrix multiplier comprises one or more 2×2 unitary optical matrices optically interconnected to implement a singular value decomposition (SVD) of a matrix, and a nonlinear optical device coupled with the optical matrix multiplier in the semiconductor substrate, to receive the optical signal outputs and to provide an optical output that is generated in a nonlinear manner in response to the optical signal outputs of the optical matrix multiplier reaching saturation or attenuation. Additional embodiments may be described and 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: Methods, apparatuses, and systems are described herein to compensate for a skew effect that occurs in an optical signal generated in response to an electrical to optical (E/O) conversion of an electrical signal carrying data received from a driver. A skew control device coupled with a driver or a modulator provides a skew to the electric signal prior to E/O conversion to compensate for the skew effect. The skew may be provided by a reverse-biased p-n junction diode. Other embodiments may be described and/or claimed.

Abstract: Thermally compensated waveguides are disclosed herein. According to one aspect, the present disclosure proposes new ways to combine negative TOC (NTOC) material layers within the waveguides. NTOC materials can be implemented in one or more of a cladding layer, a core rib/channel waveguide, a horizontally segmented waveguide, a vertically segmented waveguide, a sub-wavelength grating structure, and/or in various other waveguide structure implementations including arbitrary core or cladding shapes. The integration of NTOC materials improves the temperature dependence of the waveguide spectrum. The need for fast and efficient optical-based technologies is increasing as Internet data traffic growth rate is overtaking voice traffic, pushing the need for optical communications. The new waveguide structures can be integrated into waveguides, individual devices, integrated devices like arrayed waveguide grating devices, and photonic integration circuits (PICs), decreasing temperature dependence of such devices and circuits.
