“…Compared to the previous works, this logic device exhibits preponderance in terms of footprint and the number of logic applications. Although the footprint of the device in [39] is smaller than that of the device in this work, the logic applications provided by the device in [39] are less than in this work. Moreover, the four logic functions in [39] cannot be realized at the same time.…”

Integrated optical logic devices are essential building blocks for implementing all-optical arithmetic and logic unit. In this paper, an ultra-compact multifunctional optical logic device consisting of a rectangular ring resonator coupled with two parallel metal–insulator–metal waveguides is presented. The transmission characteristics of the structure are analyzed in detail via temporal coupled-mode theory. The finite-difference time-domain simulation results reveal that multiple logic functions can be implemented with the aid of the wavelength division multiplexing technique at different output ports. Specifically, all seven basic types of logic gates, half-adder, half-subtractor, and 2*4 decoder can be implemented by monitoring the transmission of through and drop ports at different wavelengths. More importantly, among these functions, six logic gates (OR, XNOR, NAND, NOR, XOR, and AND) and half-adder functions can be performed simultaneously; the NOT logic operation is performed with controllable output ports and selectable working wavelengths; the half-subtractor and 2*4 decoder functions can be operated simultaneously. The proposed logic device is characterized by a small area overhead, multifunctionality, fast response time, and ultrahigh-speed information processing. It may potentially be applied in on-chip universal and parallel photonic computing units.

Photonic crystals (PCs) are a field that is very important and interested in the design of a wide range of devices to control electromagnetic waves in different frequency regimes. Here, We try to introduce an all-optical device with practical applications such as fast response and high accuracy that have very critical and benchmark development in optical devices for photonic integrated circuits. In this paper, a novel modified shape 4-channel demultiplexer based on 2D-PCs by using suitable ring resonators is proposed to control light. The presented configuration includes three parts such as a direct input waveguide, a ring resonator, and four indirect waveguides for outputs of optical waves. Numerical analysis is investigated based on finite difference time domain (FDTD) method to achieve a four-band demultiplexer that has the capability to control the electromagnetic waves. Numerical results show that not only average quality factor (Q) of the 2D-PCs demultiplexer is 3969.25, but also average cross-talking value is -30.38 dB, the average transmission coefficient (T) is 0.998 and the lowest and highest channel bandwidths are 0.3 and 0.6 nm, respectively. Also, the minimum and maximum distance between any two adjacent channels is 0.6 and 1.1 nm. The all optical photonic demultiplexer has a compact footprint and occupies an area of 302 µm² and its operation is in long wavelength region. Based on the abovementioned practical performance and results, the presented optical demultiplexer is highly accurate by using a robust and low power-area that can be nominated to use photonic integrated circuits (PIC).

“…In recent years, many passive and active SPP devices such as switches [6,7], logic gates [5,[8][9][10][11][12][13][14][15][16][17][18], sensors [19,20], nanowires [21][22][23], splitters [24], flters [25,26], couplers [27], resonators [28,29], and multi-and demultiplexers have been designed [30][31][32][33].

This paper proposes a new configuration of dielectric-metal-dielectric (DMD) waveguides to design optical logic gates. Seven plasmonic logic gates, including NOT, OR, AND, NAND, NOR, XOR, and XNOR, are realized by one nanoring and four DMD plasmonic waveguides. To realize the logic gates, an ultrasmall size of 300 nm × 300 nm device is designed. The performance of the plasmonic logic gates is based on constructive and deconstructive interference between input and control ports. To evaluate the logic state of the output port, the threshold transmission limit is assumed to be 0.35. The transmission ratio, T, contrast ratio, CR, modulation depth, MD, insertion loss, IL, and contrast loss, CL, parameters measure the seven logic gates’ performance. A maximum T of 232% is obtained for AND, OR, and XNOR logic gates. Simulation results show that the dimensional parameters are optimized because of very high MD for all seven logic gates. Maximum values of CR and CL are obtained for the NOT gate. For the AND gate, a minimum IL value is achieved. The studied plasmonic logic gates can be employed in building blocks of all-optical signal-processing nanocircuits and nanophotonics devices. The finite element method (FEM) simulates the structure with COMSOL Multiphysics 5.4 software.
