Optical architectures are presented for performing fully parallel, carry-free computation with a trinary, modified signal-digit number representation to allow addition, subtraction and multiplication. Two different optical schemes involving position and polarization encoding enable the fabrication of modular trinary logic systems that accommodate trinary numbers of different magnitudes. The optical systems made up of redundant three-dimensional modules provide a designer with latitude to simultaneously carry out addition, subtraction or multiplication optically and with reduced complexity.
