Abstract
An optical vector-matrix multiplication system includes a transmitter subsystem, such as a silicon photonic transmitter subsystem or a VCSEL array, that encodes a digital input vector into a vector-encoded optical signal. One portion of a free-space optical subsystem fans out the vector-encoded optical signal along a first axis and directs it to a tunable optical metasurface. The tunable optical metasurface encodes a digital matrix as a two-dimensional matrix of optical modulation parameters and modulates the fanned-out vector-encoded optical signal to form a modulated optical signal. Another portion of the free-space optical subsystem condenses the modulated optical signal along the first axis to perform a summation and directs the optical radiation to a silicon photonic receiver subsystem, which detects and decodes the condensed optical signal.
