Abstract: An apparatus includes a photodetector and a memristor coupled to the photodetector. The photodetector is configured to receive and convert optical signals to electrical signals to program the memristor to an on or off state. The apparatus further includes a ring resonator coupled to the memristor and configured to modulate light based on the on or off state of the memristor.

Abstract: Systems, devices, and methods are provided for all-optical reconfigurable activation devices for realizing various activations functions having normalized output power. The device and systems disclosed herein include an interferometer comprising a first branch formed of a first waveguide and a second branch formed of a second waveguide. A resonator cavity is coupled to the second first waveguide and at least one phase-shift mechanism is coupled to one of the second waveguide and the resonator cavity. The at least one phase-shift mechanism is configured to control biases of the interferometer to achieve a desired activation function at an output of the interferometer, and an optical amplification mechanism is coupled to the output of the interferometer and configured to add optical gain to the desired activation function.

Abstract: A device may include: a highly doped n+ Si region; an intrinsic silicon multiplication region disposed on at least a portion of the n+ Si region, the intrinsic silicon multiplication having a thickness of about 90-110 nm; a highly doped p− Si charge region disposed on at least part of the intrinsic silicon multiplication region, the p− Si charge region having a thickness of about 40-60 nm; and a p+ Ge absorption region disposed on at least a portion of the p− Si charge region; wherein the p+ Ge absorption region is doped across its entire thickness. The thickness of the n+ Si region may be about 100 nm and the thickness of the p− Si charge region may be about 50 nm. The p+ Ge absorption region may confine the electric field to the multiplication region and the charge region to achieve a temperature stability of 4.2 mV/° C.

Abstract: Systems and methods are provided for performing element-wise multi-vector multiplication. An example includes a waveguide to receive an input optical signal encoded with a first vector and output an output optical signal. One or more optical-to-electrical (O/E) converters are provided to receive one or more optical signals encoded with one or more vectors and generate one or more electrical signals based on the received one or more optical signals. One or more optical modulators are optically coupled to the waveguide and electrically coupled to the one or more O/E converters, the one or more optical modulators modulate an intensity of the input optical signal on the waveguide based on the one or more electrical signals. The output optical signal is encoded with a product of the first vector and the one or more vectors.
