Integrated optical circuits with nanophotonic devices have attracted significant attention due to their low power dissipation and light-speed operation. With light interference and resonance phenomena, the nanophotonic device works as a voltage-controlled optical pass-gate like a pass-transistor. This article first introduces the concept of optical pass-gate logic and then proposes a parallel adder circuit based on optical pass-gate logic. Experimental results obtained with an optoelectronic circuit simulator show the advantages of our optical parallel adder circuit over a traditional CMOS-based parallel adder circuit.
