Abstract: An example device includes a doped absorption region to receive optical energy and generate free electrons from the received optical energy. The example device also includes a doped charge region to increase an electric field. The example device also includes an intrinsic multiplication region to generate additional free electrons from impact ionization of the generated free electrons. The example device includes a doped contact region to conduct the free electrons and the additional free electrons.

Abstract: Plasmonic avalanche photodetection employs an optical antenna and an avalanche photodiode (APD) coupled to the optical antenna. Hot carriers generated by light incident on the optical antenna are received in an avalanche multiplication region of the APD where avalanche multiplication of the hot carriers is provided.

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.
