The propagation characteristics of a double-half inverse Gaussian hollow beam (DHIGHB) through atmospheric turbulence are investigated theoretically. The on-axis average intensity of the beam passing through a turbulent atmosphere is derived in closed-form under the framework of the Huygens–Fresnel diffraction integral and the Rytov method. Numeric...

The fiber optic link is one of the main segments of up-to-date telecommunication systems. Developing low cost, ultra reliable systems with very low latency for massive machine to machine and enhanced broadband mobile networks is a hot research topic. Motivated by this we investigated the polarization multiplexing technique applicable in fiber optic...

In present work, we propose a surface plasmon resonance based D-shaped fiber for the chemical sensor using nanoscale silver strip deposited over polished surface of single mode fiber. Various parameters of the designed sensors are optimized to achieve the maximum wavelength sensitivity. The sensing properties are investigated using finite element m...

In this paper, a two-dimensional structure based on photonic crystal for adding three input bits is proposed. The dielectric rods used in this work are made of chalcogenide with a dielectric constant of 9.61. The lattice constant of the structure is 510 nm and the radius of the fundamental rods is 0.206 times the lattice constant. Three waveguides ...

We have investigated structural and optical properties of gallium oxide (Ga2O3) thin films deposited on pre-cleaned fused quartz substrates at room temperature by RF sputtering method. The as-prepared and annealed Ga2O3 thin films are characterized by X-ray diffraction, energy dispersive X-ray fluorescence, fluorescence spectrometer and a double be...

In this work, the effect of the temporal instability on stimulated Raman scattering (SRS) characteristics in a high power Yb-doped fiber amplifier is studied experimentally and theoretically. It is found that the SRS intensity is strongly influenced by the type of the seed source. When the power amplifier is seeded by a normal fiber oscillator lase...

In this research article, a 3C–SiC-based single-junction solar cell is evaluated using a two-dimensional finite element method. Effects of n + and p + thicknesses and operating temperature on the performance of n + pp + 3C–SiC solar cell are simulated to find its real efficiency. For a cell with a thickness of 5 µm, the efficiencies of 12.52%, 11.2...

Optical management and design is one of the most effective methods to unlock the full potential of photocurrent density and power conversion efficiency for perovskite solar cells (PSCs). However, the common-used optical designs are still limited by the near-infrared response. Here, we proposed an effective optical structure in PSCs by texturing the...
