A micro-current source using the drive electron mobility model is proposed by non-linear micro-ring resonator. The system consists of a nonlinear microring resonator known as Panda ring made InGaAsP/InP. stacked waveguide (plasmonic island) silicon-graphene-gold formed at center ring, through which whispering gallery mode (WGM) light can be controlled and generated central it allows driven within gold layer that increase WGM beam acceleration device current density with respect to input...
A new photonics biosensor configuration comprising a Double-side Ring Add-drop Filter microring resonator (DR-ADF) made from SiO2-TiO2 material is proposed for the detection of Salmonella bacteria (SB) in blood. The scattering matrix method using inductive calculation used to determine output signal’s intensities blood with and without presence Salmonella. change refractive index due reaction its applied antibody on flagellin layer loaded sensing detecting microresonator causes increase...

Abstract Laser Surface Smoothing (LSS) is a widely used technique for improving the surface quality of materials, particularly in additive manufacturing (AM), where high roughness and porosity are prevalent. Despite benefits LSS, faces challenges due to fluctuation input parameters, such as laser power scanning speed, leading inadequate smoothening. Hence, this study ultilised processing temperature which has been determined via near-infrared spectroscopic method monitoring parameter LSS....
Abstract One-dimensional (1D) Ni-doped ZnO nanorods have been synthesised using two techniques: non-vacuum spray pyrolysis and sol-gel immersion. The work investigated the influence of Ni dopant on structural, morphological, optical, magnetic characteristics undoped by numerous analytical techniques including X-ray diffraction, scanning electron microscopy, UV-Vis spectrometer, vibrating sample magnetometer. material displays enhanced structural characteristics, such as vertically orientated...
Abstract Water pollution caused by organic dyes, particularly methylene blue (MB), poses a significant environmental challenge. This study investigates the novel application of laser-enhanced photodegradation MB using cerium oxide (CeO 2 ) nanostructures (NSs) as semiconductor photocatalyst. CeO NSs were synthesized via precipitation method employing Ce(NO 3 ·6H O and NaOH at room temperature, followed calcination 600°C for hours. The structure was analysed XRD, FTIR, EDX, SEM FESEM. To our...
Abstract A sensitive tapered optical fiber sensor incorporating graphene oxide (GO) and polyvinyl alcohol (PVA) composite film for the rapid measurement of changes in relative humidity was proposed experimentally demonstrated. The sensing principle based on intensity modulation transmitted light induced by refractive index coatings. region obtained tapering a section single-mode (SMF) from its original 125 µm diameter down to 9.03 µm. structure then modified through deposition GO/PVA...
We have proposed the simple method of squeezed light generation in modified microring resonator, which is known as conjugate mirror (MCM). When monochromatic input into MCM, general form coherent states for a quantum harmonic oscillator can be generated by controlling additional two side rings, are phase modulators. By using graphical called Optiwave program, within an MCM obtained and interpreted amplitude, phase, quadrature photon number-squeezed states. This has shown potentials related...
