In this paper, the concept of photonic crystals (PhCs) is fundamental to designing and simulating an all-optical logic gate device. We proposed an all-optical switch composed of two-dimensional (2D) photonic crystal waveguides with a central photonic crystal ring resonator (PCRR). The new all-optical NAND logic gate device comprises two linear waveguides coupled to each other through a single compact PCRR. The plane wave expansion (PWE) and finite-difference time-domain (FDTD) methods are applied to simulate the properties of the system. The structure is implemented on the operational wavelength of 1700 nm on an air wafer of only 12 μm × 12 μm. Indeed, the simulation results show that the proposed all-optical NAND gate is a strong candidate for ultrafast photonic integrated circuits (PICs) for applications in optical communications, being advantageous with high transmitting power, with simple design, and without the use of optical amplifiers and nonlinear materials.

“…Optical devices exhibit sufficient transmission performance to reduce these effects and enable reliable data transmission to multiple points simultaneously (Murphy 2020). Techniques such as wavelength division multiplexing and demultiplexing have paved the way to effectively provide the capacity of optical devices (Hu et al 2011;Zhang et al 2017;Si and Cheng 2003). The increasing interest in integrated optical circuits for high-speed signal processing has diversified the efforts to improve their performance (Khonina et al 2022).…”

Confinement of the light at the subwavelength scale makes photonic devices more efficient in applications such as optical filtering, switching, and sensing with their low dimensions. Metal-insulator- metal waveguide-based configurations present many paths for manipulating light at the wide range of the electromagnetic spectrum. For that purpose, in this study, a wavelength demultiplexer (WDM) based on a metal-insulator-metal (MIM) waveguide is numerically investigated by finite difference time domain (FDTD) method. Proposed WDMs have cascade polygon resonators. After optimizing the fundamental filter, this structure is formed as 1×N demultiplexers. The proposed demultiplexers have two- and three channels. The minimum full width at half-maximum (FWHM) value for these channels is 20.02 nm and the maximum quality factor value is 47.7 at 954.9 nm wavelength. The minimum crosstalk value is obtained as -30.37 dB for this study. The proposed 1×N demultiplexers have potential tools to design low-cost integrated optical circuits for specific wavelengths.

“…Interferometer, Mach-Zehnder interferometer (MZI) [3,4], semiconductor optical amplifiers (SOA) [5], and nonlinear [6] phenomena such as electro-optical phenomenon, thermal optical effect and two-photon absorbance were used to develop PhC-based all-optical logic gates (LoG) [7,8]. All-optical Buffer, AND [9,10], and OR [11] (BAO) LoG have been employed in optical combinational and sequential systems including optical detectors, resonators, and LoG [12][13][14][15][16][17][18]. Random noise, intricate structure, and gain saturation effects are some of the concerns of the ways to manufacture all-optical LoG.…”

Optical gadgets will take the role of electronic devices in the following decade due to their fast speed, low power consumption, and low heat tolerance. As a consequence, photonic crystal (PhC) based all-optical Buffer, AND, and OR (BAO) logic gates (LoG) were constructed by exploiting square lattice silicon rods with an air background. The suggested LoGs function efficiently by altering the phase of light beams having a wavelength of 1550 nm and are working on the beam-interference principle. The structure is modeled and tested through the finite-difference timedomain (FDTD) approach. For each logic gate, the performance parameter of extinction ratio (ER) is determined by tweaking the silicon rod radius and refractive index over a set of parameters. The suggested all-optical BAO LoG has extinction ratios of 11.84 dB, 33.9 dB, and 11.65 dB, respectively. The response time and operating speeds for each input combination are also calculated and tabulated. The processing speeds of BAO were observed to be 38 THz, 27.7 THz, and 38.46 THz, respectively.
