Novel architecture of the smart optoelectronic logic circuit based on directional couplers

Abstract

The novel architectures of the smart optoelectronic logic gate has been proposed for the first time. In former one, both the AND and OR function can be integrated in a single circuit. These optoelectronic circuits are composed of the integrated optical waveguide directional couplers, optoelectronic converters, EDFAs, delay line, and a DFB laser. Importantly, linear device operation with low power is the main advantage as compared to the conventional optoelectronic logic elements. Moreover, characteristics of these optoelectronic circuits, such as optical path, slew-rate limiting, and phase retardation on the different states of operation, have been discussed and would be informative.
