“…The straight waveguides and ring resonators are separated by a spacing distance (d) of 5 nm. The Johnson and Christy data model was employed in our simulation design to characterize the permittivity of the metal material, which was silver [24], and the insulator material's refractive index (n) was 1.292. The operation wavelength of 1,550 nm was chosen for use in our proposed system due to its numerous applications in optical communications.…”

In this paper, we report new nanoscale plasmonic multiple inputs logic gates based on insulator-metal-insulator (IMI) nanoring waveguides. The proposed all-optical gates are numerically analyzed by the finite element method. NOT, AND, NAND, NOR, and EX-NOR all-optical logic gates were suitably designed and investigated based on the linear interface between the propagated waves through the waveguides. The operation wavelength was 1550 nm. The simulation results show that the optical transmission threshold of (0.26) which performs the operation of planned logic gates is accomplished. Moreover, simulation results show that our compact structure of all-optical logic gates may have potential applications in all-optical integrated networks.

The main purpose of this study is to design combinational logic gates based on a novel configuration of insulator–metal–insulator (IMI) nanoring plasmonic waveguides. Plasmonic logic gates are half adder, full adder, half subtractor, full subtractor, and one-bit comparator and are realized in one structure. The performance of the logic circuits is based on constructive and destructive interferences between the input and control signals. The transmission threshold value is assumed to be 0.35 at the resonance wavelength of 1.310 μm. The transmission spectrum, contrast loss (CL), insertion loss (IL), modulation depth (MD), and contrast ratio (CR) are calculated in order to evaluate the structure’s performance. The maximum transmission of the proposed structure is 232% for full a adder logic gate, and MD exceeds 90% in all plasmonic combinational logic circuits. The suggested design plays a key role in the photonic circuits and nanocircuits for all-optical systems and optical communication systems. The combinational logic gates are analyzed and simulated using the finite element method (FEM).

“…Among several optical parameters, including emission intensity, spectrum shape, fluorescence lifetime, bandwidth, and spectral shift, Fluorescence Intensity Ratio (FIR) stands out as the most accurate and reliable optical parameter for temperature monitoring due to its remarkable ability to prevent self-referencing [84][85][86][87]. FIR-based upconversion nano-thermometry could also be applied in various fields, including anti-counterfeiting [88], optical rotation [89,90], nonlinear properties [91,92], temperature-controlled integrated circuit devices [93][94][95], temperature-sensitive cancer or antibiotic therapies [96,97] and temperature calibration for gas sensing [98]. Nanoparticle ensembles have been prevalent in most temperature measurements based on upconversion nanoparticles [99][100][101].…”

The optical characteristics and varied applications of lanthanide-doped NaYF4 upconversion nanocrystals have received considerable interest in recent years, such as in ratiometric thermometry. This review thoroughly examines the various synthesis processes utilized in producing these nanocrystals and their application in temperature sensing. Synthesis of NaYF4 upconversion nanocrystals is a complex procedure that requires careful management of dopant concentrations, crystal phase, size, and shape. The distinctive luminescent characteristics of lanthanide ions, which facilitate the transformation of photons with low energy into emissions with higher energy, render NaYF4 nanocrystals suitable for ratiometric thermometry applications. We explore the fundamental concepts underlying upconversion luminescence in developing ratiometric temperature sensors. In this discourse, we examine the selection of lanthanide dopants, the mechanics underlying their energy transmission, and the development of customized sensor architectures. This review covers the recent progress and utilization of NaYF4 upconversion nanocrystals in ratiometric thermometry, including diverse areas such as biological temperature detection, environmental surveillance, and materials research. We evaluate the obstacles and potential advancements in this domain, specifically emphasizing approaches to improving temperature sensors' precision, responsiveness, and applicability based on upconversion.
