Abstract
The provided is a multi-functional integrated photonic neural network processing device, including: an input layer consisting of a series of waveguides configured to receive incoming optical signals (input array); an interferometer layer connected to the input layer comprising Mach-Zehnder Interferometers (MZIs) configured to apply linear transformations to a series of optical signals received from the input; an output layer connected to the interferometer layer comprising a series of waveguides configured to direct the optical signals from the interferometer layer to the output (output array); a pair of couplers and a pair of phase shifters located on each Mach-Zehnder Interferometer (MZI); and each phase shifter comprising a waveguide with an adjustable width and an adjustable length.
