In this digital era, all-optical logic gates (OLGs) proved its effectiveness in execution of high-speed computations. A unique construction an OR, NOR, and NAND based on the notion power combiner employing metal–insulator-metal (MIM) waveguide Y-shape with a minimal imprint 6.2 µm × 3 is presented structure evaluated by finite-difference time-domain (FDTD) technique. The insertion loss (IL) ext...

A three-component molecular ensemble consisting of the constitutionally dynamic cage 1, rotaxane 2 and luminophore 3 acts as a signal transducer which assimilates three input signals, i.e., Zn2+, H+, Cu+, to perform individual logic operations (e.g. 3-input NOR gate with catalytic output, AND optical output ) operates an unconventional demultiplexer .

The circular dichroism of hypothetical, water-filled, spherical shells, 75-3500 nm in radius, with walls 7.5 nm thick, composed of poly(L-lysine) in various conformational proportions, and suspended in water, were computed from the known optical properties of this polypeptide by classical general light-scattering theory (Mie theory). Comparison of the computed curves of circular dichroism spect...

in this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (mqw) chirped distributed feedback semiconductor optical amplifier (dfb-soa)  all-optical flip-flop is precisely derived. we have analyzed the effects of strains of qw and mqw and cross phase modulation (xpm) on the dynamic response, and rise and fall times of the ...

To mitigate antibiotic residues in the water environment, Bi2Sn2O7/g-C3N4 (BSCN) heterojunction was fabricated by a facile ultrasound-assisted hydrothermal method. The microstructure, morphology, and optical properties of studied XRD, FTIR, XPS, SEM, TEM, UV–Vis DRS, PL. degradation rate 20 mg/L norfloxacin (NOR) under visible light for 3 h adopted as one indexes to evaluate photocatalytic perf...

A gradual transition from electrical to optical networks is accompanying the rapid progress of telecommunication technology. The urge for enhanced transmission capacity and speed is dictating this trend. In fact, large volumes of data encoded on optical signals can be transported rapidly over long distances. Their propagation along specific routes across a communication network is ensured by a ...
