“…4 There are three PhC configurations actively researched and those are one-dimensional (1D), two-dimensional (2D), and threedimensional (3D), and each dimension has its specific applications and advantages on each other. The 2D PhC [5][6][7][8][9][10][11][12][13][14][15] is quite popular in the demonstration of photon propagation in several applications, such as switches, optical filter, sensor, and cavity quantum electrodynamics. PhC has PBG due to its periodic dielectric structure and different frequency 16 and can be used in many applications, including the fabrication of lossless dielectric, mirrors, and resonant cavities for optical light.…”

In this article, we report modeling, simulation, and analysis of shifting 2D photonic crystal cavity side holes in GaN-AlN-sapphire layered structure. The design was simulated with Lumerical finite-difference time-domain. A lattice constant a, 157 nm, and a hole diameter d, 106 nm, were used in the design. The cavities are based on L3, which we demonstrated by simply shifting two holes away from a line cavity with distances of 132, 142, and 152 nm, respectively. The highest quality factor, Q, value achieved is 2.25 × 104 at 152-nm cavity distance.

“…Albeit, they have a decreased FoM due to their higher losses. In contrast, PhC-based RI sensors tend to have lower losses and they are able to provide a higher FoM 38 – 42 . However, PhC sensors commonly exhibit a small field overlap with the analyte, ensuing in lower sensitivity as compared to plasmonic sensors.…”

In this paper, an optical refractive index (RI) sensor based on a hybrid plasmonic-photonic crystal (P-PhC) is designed. In the sensor’s structure, some metallic rods are embedded in a rod-type photonic crystal (PhC) structure. Numerical simulations are performed based on the finite-difference time-domain (FDTD) method. The obtained results illustrate that the localized surface plasmons (LSP) induced by metallic rods can be excited in a PhC lattice to generate a hybrid P-PhC mode. According to the results, the hybrid mode provides unique opportunities. Using metallic rods in the coupling regions between waveguides and the resonant cavity significantly increases the interaction of the optical field and analyte inside the cavity. The simulation results reveal that high sensitivity of 1672 nm/RIU and an excellent figure of merit (FoM) of 2388 RIU−1 are obtained for the proposed hybrid P-PhC sensor. These values are highest compared to the purely plasmonic and or purely PhC sensors reported in the literature. The proposed sensor could simultaneously enhance sensitivity and FoM values. Therefore, the proposed hybrid P-PhC RI sensor is a more fascinating candidate for high-sensitivity and high-resolution sensing applications at optic communication wavelengths.

“…In recent years, these crystals have attracted great attention in many cases due to their use in electronics, telecommunications, and optical information processing [2]. In these years, photonic crystals based on photonic crystals have been very much considered due to photonic crystal features such as low losses, very low bandwidth, exibility in shape and dimensions, as well as suitability for integrated circuits in Nano scale dimensions [3,4]. In general, crystals photons structures of dielectric materials, and given that the refractive index of one, two and three dimensions periodically with a period of about a wavelength of light varies, divided into three main groups, the next one, two-dimensional and three -dimensional.…”

The optical communications have been the backbone of the most dramatic developments in telecommunications systems in the past two decades, so that the current world of communications is unthinkable without the infrastructure of ber optic networks. Also, the speed and bandwidth of optical devices have expanded the development of optical telecommunication systems, so the design, simulation and fabrication of optical devices have become more and more respected by researchers in this eld. In this paper, a design for optical narrow Band Pass Filter (BPF) using two-dimensional (2D) photonic crystals (PCs) is presented that are suitable for applications in optical ber communications (third window) in Wavelength-Division Multiplexing (WDM) systems. BPF was simulated by a two-dimensional timing method (FDTD) Finite-difference time-domain (FDTD). Also, the plane-wave expansion (PWE) method was used to evaluate the bands and calculate the Photonic Band Gap. Simulation results show this desired structure, acts as a very sharp optical BPF in the central wavelength of 1550 nm (In order to minimize attenuation). Normal voltage transmission e ciency, full width at half maximum (FWHM), and Focal Plane Module (FPM) for proposed BPF were 94.8%, 2583 and 0.6 nm, respectively.
