A photonic tensor multiplier system multiplies a first tensor with a second matrix. It includes a splitter that receives light at N wavelengths from a light source and divides the light into N separate beams. N first optical modulators modulate the beams with time-multiplexed column vector signals from the second matrix. An arrayed waveguide grating router (AWGR) processes the N modulated signals. M of the AWGR output signals are split into K x M beams and modulated again by K x M second optical modulators that modulate with time-division-multiplexed row vectors of the first tensor. K x M demultiplexers each output signals at the N different wavelengths. An integrator coupled with a demultiplexer output integrates the signal to obtain an accumulated multiplied signal, representing a value of the photonic tensor multiplier output tensor. Optical components of the system may be integrated in one or more photonic ICs (PICs).

The invention provides a photoelectric collaborative data high-speed switching system. The photoelectric collaborative data high-speed switching system comprises an electric processing unit, an optical switching unit and an optical switching controller, the electric processing unit receives a data frame, splits the data frame into a plurality of cell slices, and allocates a cache address to each cell slice; the optical switching controller receives the request sending message, inquires wavelength scheduling configuration information according to destination address information in the request sending message, and generates a wavelength scheduling control instruction; the optical switching unit receives the wavelength scheduling control instruction, controls the conduction state of the controllable optical switch array according to the wavelength scheduling control instruction, and establishes an optical channel from a source end to a destination end by using the wavelength routing characteristic of the arrayed waveguide grating router; and the electric processing unit is also integrated with a remote direct memory access unit which outputs the cache address and the data length of each cell slice after receiving the sending permission message, so that the target-end electric processing unit directly reads the cell slices from the source-end cache and recombines the cell slices into data frames.

A photonic matrix multiplier multiplies an MxP first matrix with a PxN second matrix. The multiplier includes a splitter that receives light including M different wavelengths into M separate light beams. M first optical modulators modulate the M light beams with time-multiplexed row vectors of the first matrix. An arrayed waveguide grating router (AWGR) processes the output signals of the M first optical modulators and outputs N processed light signals. N second optical modulators modulate the N processed light signals with time-multiplexed column vectors of the second matrix. N demultiplexers separate the N second optical modulator output signals in light beams at each of the M different wavelengths. Integrators integrate demultiplexer output signals to obtain multiplied and accumulated signals.
