In this paper, a compact and highly sensitive refractive index plasmonic sensor, with a metal-insulator-metal waveguide coupled with a notched hexagonal ring resonator and the stub is proposed. Structural parameters of the sensor have a key role in the sensor's sensitivity and transmission spectrum, which are investigated using the finite-difference time-domain method embedded in the commercial simulator R-Soft. The results yield a linear link with the refractive index of the material under testing and its wavelength resonances. Moreover, the maximum linear sensitivity is S = 2547 nm/RIU, its corresponding sensing resolution is 3.92 × 10 −6 RIU. Therefore, this sensor can be implemented in high-performance nano-sensors and biosensing devices. In this proposed structure, the positions of transmission peaks can be easily manipulated, by adjusting the length and width of the stub.

“…The rod represented by the solid cylinders corresponding to (SiO 2 /TiO 2 or SiO 2 /ZrO 2 ) material of low refractive index which varied in the range of 1.51 to 1.58 at λ = 1.55 µm. We can produce rods of the refractive index which is within the range from the refractive index of pure silica (N = 1.4) to the refractive index of titania (N = 2.3) [16,17]. The rods of low refractive indexes afford the possibility to produce planar systems, which are compatible with optical telecommunication.…”

Quality factor of two-dimensional photonic crystals microcavity fabricated by SiO2/ZrO2 or SiO2/TiO2 in which the refractive index varied in the range of 1.51 to 1.58 has been investigated in the present paper. The structure studied consists of circular rods of radius r embedded in air slab, while a is the constant of triangular lattice. Finite difference time domain method with perfectly matched layers was used to calculate the transmission spectrum by FullWAVE software. The results of simulation clearly demonstrate the existences of resonance wavelength of which the position and the highest Q (Q ≈ 4 × 10 5 ) value are strongly affected by refractive index. We demonstrate that the calculated Q factor for the designed cavity increases by a factor of three relative for a cavity without increasing the refractive index.

The IV semiconductor materials have a pivotal role in photovoltaic (PV) systems. Research on the optimal grating structure has attracted a lot of interest because of its potential application in light-trapping in thin film PV cells. The Photonic Crystals (PCs) with their nano-engineered feature which allowed them to obtain high efficiency solar cells in particular from a parametric aspect. By using the Rigorous Coupled Wave Analysis (RCWA) method by RSoft CAD software, a Gallium arsenide (GaAs) thin film is studied with a simple trapezoidal grating of PCs to improve optical absorption with height, width and the mixed ultra-precision grating variations taking into account the J-V solar cell characteristics. According to our simulation results and compared to the planar grating, an enhancement in the power conversion efficiency (η) of 53.72% with a one dimensional PCs grating, and a 115.36% improvement with a simple trapezoidal grating. Furthermore, by mixing the ultra-precision values of the gratings we have an enhancement of 147.25% in height variation and 151.04% in width variation, with a noticeable improvement in the width effect compared to the height that reached up to 58.22%.
