Abstract
Method and apparatus are provided for NLO switching by first providing an amorphous waveguide (wg) encoded with gratings which produce phase-matched SHG in at least two wg modes. Then two input pulsed laser beams (preferably beams split from the same source) are directed into and propagate in the wg, one beam in each of the two modes so as to generate two phase-matched SHG beams in one mode by the use of gratings of the invention. The fundamental beams produce SHG beams which are about 180.degree. out of phase with each other. The two input beams are adjusted such that some of the pulses in their respective pulse trains overlap spatially and temporally, interfere and are cancelled to output a data signal in a resultant pulse train. A detector then reads and processes the output signals. Such NLO switch will allow integrated circuitry to operate at faster rates and to allow, e.g. aircraft to communicate, switch, compute, sense, display and respond much faster than state-of-the-art circuitry based on electronics switching.
