Abstract In this digital era, all-optical logic gates (OLGs) proved its effectiveness in execution of high-speed computations. A unique construction of an all-optical OR, NOR, NAND gates based on the notion of power combiner employing metal–insulator–metal (MIM) waveguide in the Y-shape in a minimal imprint of 6.2 µm × 3 µm is presented and the structure is evaluated by finite-difference time-domain (FDTD) technique. The insertion loss (IL) and extinction-ratio (ER) for proposed model are 6 dB and 27.76 dB for NAND gate, 2 dB and 20.35 dB for NOR gate and 6 dB and 24.10 dB respectively. The simplified model is used in the construction of complex circuits to achieve greater efficiency, which contributes to the emergence of a new technique for designing plasmonic integrated circuits.

AbstractOptical NAND gate is a universal gate which can be used for implementing different kinds of combinational circuits without using other gates. Due to significance of optical NAND gates in the optical communications, in this paper we proposed a novel structure for designing an all optical NAND gate based on photonic crystal structures. The proposed structure was designed using threshold switching mechanism which can be implemented using nonlinear ring resonators. In the proposed structure delay time is about 2.3 ps.
