Abstract

Three classes of integrated optical devices suitable for implementing general combinatorial logic are discussed. The categories considered are electric-electric-optic (EEO), electric-optic-optic (E00), and optic-optic-optic (000). Existing gate geometries based on electro-optic Bragg gratings are modified to permit the realization of the NOT, NAND, OR, NOR, and inhibition functions. A full-adder based entirely on electro-optic Bragg gratings is developed, and the device is compared to current VLSI technology in terms of size and speed. The use of programmable logic arrays (PLA's)for implementing general combinatorial logic is discussed. The paper concludes with a proposal for using electro-optic Bragg gratings to construct an integrated optical PLA.
