Abstract

Matrix-vector multiplication is accomplished by continuous wave polarized ght energy transmitted along a plurality of optical waveguides through modulation by a first optical modulator in response to a column vector type input signal and additional modulation by a second optical modulator in response to a row vector type input signal. The resultant modulated light energy outputs are received by a polarization analyzer for transforming modulations in polarization and phase to commensurate amplitude modulations. A photo-responsive storage and integrating means receives the light energy associated with each of the optical waveguides and develops a cumulative signal representative of the matrix-vector multiplication.
