PCT No. PCT/GB86/00288 Sec. 371 Date Jan. 12, 1987 Sec. 102(e) Date Jan. 12, 1987 PCT Filed May 21, 1986 PCT Pub. No. WO86/07166 PCT Pub. Date Dec. 4, 1986.An optical logic device comprises a source of substantially constant, incoherent, optical power. Optical signal output means such as a waveguide switch receives the optical power from the source and has two output ports. The waveguide switch is responsive to electrical control signals selectively to generate optical signals on its output ports. A photodetector detects the logical condition of an optical input signal and generates a corresponding electrical control signal for controlling the waveguide switch. The arrangement is such that the optical condition of the output port is the logical complement of the logical condition represented by the optical input signal.
