“…The COMSOL multi-physics 4.2 software has been employed to simulate and design the proposed structure. An outer boundary known as perfectly matched layer (PML) has been applied for diminished nonphysical scattering with a thickness of 10% following the articles [30][31][32][33]. Figure 1(c) visualizes the modal intensity of the proposed structure and it is nicely exhibited that light is tightly confined through the core region.…”

A novel benzene core photonic crystal fiber (BC-PCF) is proposed for plasma sensing applications. The proposed BC-PCF parameters have been tuned to gain high sensitivity, high numerical aperture (NA), and low confinement loss, and modality over the extensive variety of 0.7 m to 1.9 m wavelength. The explored results for the ideal structure have exhibited the high sensitivity up to 77.84% and negligible confinement loss of 7.9 × 10-3 dB/m at 1.3 m wavelength. The V-barometer remains under 2.405 over the whole working wavelength. So the proposed BC-PCF is a single mode fiber, which advances the long partition correspondence applications. Furthermore, high numerical aperture (NA) makes the fiber potential candidate in medical imaging applications. The plan of the sensor is to find out the creative potential outcomes in sensing applications.

“…Zeonor is used as the background material of the reported RH-CPCF sensor. To compare with recent published articles [22][23][24][25][26][27][28][29][30][31][32][33][34], the proposed RH-CPCF shows the better performance of sensitivity and confinement loss are 76.44%, 77.16%, 73.20% and 2.33 × 10 −03 dB/m, 3.07 × 10 −06 dB/m, 2.84 × 10 −02 dB/m for ethanol, benzene and water respectively at 1 THz frequency. So, this suggested RH-CPCF is highly useful in biomedicine and industrial chemicals research for sensing applications in the terahertz frequency range.…”

In this article, a new design of circular cladding with a rotated-hexacore in photonic crystal fiber (RH-CPCF) has been suggested for chemical sensing application in the THz regime. The five layers circular cladding and two layers rotatedhexacore in circular shape are designed here. All numerical results are obtained with a procedure of finite element method and perfectly match layered boundary condition in terahertz (THz) wave propagation. After the simulation result, the proposed RH-CPCF shows the high relative sensitivity is 76.44%, 77.16% and 73.20% for three chemicals such as Ethanol (n = 1.354), Benzene (n = 1.366) and Water (n = 1.330) at 1 THz. On the other hand, the low confinement losses are 2.33 × 10 −03 dB/m, 3.07 × 10 −06 dB/m and 2.84 × 10 −02 dB/m for same in three chemicals at 1 THz. Moreover, effective area, effective mode index and total power fraction in core air holes are also briefly described here. In addition, this proposed circular photonic crystal fiber (RH-CPCF) can be used especially for chemical sensing in biomedical, industrial quality control, material research, micro-optics and many communication applications in THz technology.

“…The first PCF were proposed as an optical waveguide. However, due to the excellent optical performance, it holds many real applications in various areas such as gas sensor [5], chemical sensor [6], pressure sensor [7], salinity and temperature sensor [8], optical multiplexer and demultiplexer [9][10][11], optical power splitter [12], optical filter [13], etc.…”

A novel hexahedron fiber has been proposed for biomedical imaging applications and efficient guiding of terahertz radiation. A finite element method (FEM) has been applied to investigate the guiding properties rigorously. All numerically computational investigated results for optimum parameters have revealed the high numerical aperture (NA) of 0.52, high core power fraction of 64%, near zero flattened dispersion of 0.5 ± 0.6 ps/THz/cm over the 0.8–1.4 THz band and low losses with 80% of the bulk absorption material loss. In addition, the V–parameter is also inspected for checking the proposed fiber modality. The proposed single-mode hexahedron photonic crystal fiber (PCF) can be highly applicable for convenient broadband transmission and numerous applications in THz technology.
