In this paper, a polarization filter based on hybrid silver-graphene coated pentagonal Photonic Crystal Fiber (PCF) is proposed. The finite element method is used to analyse the confinement loss characteristics of the proposed PCF. The proposed PCF based filter selects the desired X-polarization mode with a low confinement loss of 0.12 dB/cm and 0....

This study has been aimed to explore the effect of dye concentration, cell thickness, and polymers on the characteristics of random laser (emission spectrum, full width at half maximum (FWHM), and lasing threshold). It has been found that the properties of the random laser are affected by these three parameters significantly, as it was observed tha...

In this research, Ag+ and Al3+ doped CuInS2 (CIS) nanoparticles were synthesized by a low-cost and non-vacuum hydrothermal method. The CuInS2 nanoparticles were synthesized by the stoichiometric ratio of (1Cu: 1In: 2S) using the hydrothermal method at 180℃ and for 16, 18 and 20 h. Afterward, Ag+ and Al3+ ions were doped with non-stoichiometric comp...

In this paper, a new model of multi-layer metamaterial perfect absorber (MPA) in the terahertz region has been introduced. This model is similar to the classic absorber model, ie the three traditional layers of metal-dielectric-metal. The difference is that the middle layer has changed in height and consists of 3 separate layers with the same mater...

In the course of past decade, surface plasmon resonance (SPR) based photonic crystal fiber (PCF) sensors have shown phenomenal advancement. Many researchers have proposed a wider range of SPR-based sensors by this time. But many of these proposed sensors either show low sensitivity or it is very difficult to fabricate the sensors for real time appl...

In this research, an all-optical half-subtractor is designed and simulated using two-dimensional photonic crystals. First, a photonic crystal structure is created using Si rods in the air context to obtain the optical half-subtractor. Afterward, using point and line defects, two waveguides are created for the input and two waveguides are created fo...

In this paper we have studied the geometrical and material aspects of plasmonic nanoparticles embedded within organic–inorganic halide Perovskite solar cells (PSCs), to achieve higher solar absorbance enhancement. The material choice of the nanoparticle employed within the film is proportional to the enhancement factor the cell. Interestingly, we o...
