Abstract
An optical switch (100) is disclosed for switching spatially-separated complementary optical signals from a row of a two-dimensional input storage array (132) to a selected row of a two-dimensional ouptut storage array (133). The switch includes an input system (101) for converting temporally-separated information represented by a serial bit stream of complementary optical signals into a spatially-separated format for storage in the input array. An output system 105 is also included for converting the switched, spatially-separated information in the output array into a temporally-separated format for serial transmission on plurality of optical output fiber pairs 160(1)-160(N). The input and output systems enable the switch to perform both time- and space-division switching with only a single stage of switching. A distributor system (103), also included in the switch, spatially distributes the optical signal pairs from a row of the input array over the entire output array for selective storage of the information represented by the signals in one or more rows of the output array.
