Claim 39:
40. A method comprising:
encoding a set of input values representing elements of an input vector on respective optical signals;
encoding a set of coefficients representing elements of a matrix as amplitude modulation levels of a set of optical amplitude modulators coupled to the optical signals, where at least one of the optical amplitude modulators including an input port and two output ports provides a pair of related optical signals from the two output ports such that a difference between amplitudes of the related optical signals corresponds to a result of multiplying an input value by a signed matrix element value; and
encoding a set of output values representing elements of an output vector on respective electrical signals, where at least one of the electrical signals is in the form of a current whose amplitude corresponds to a sum of respective elements of the input vector multiplied by respective elements of a row of the matrix.
