“…An optimal strut thickness is retained to prevent manufacturing difficulty during the whole process. A variety of strut widths, S, of 10 µm and 20 µm are considered, In current manufacturing methods, a 6.5 µm strut width is bearable [27,34,35]. The PML has a radius of 1710 µm with a thickness of 185 µm.…”

For the quick identification of diverse types of cancer/malignant cells in the human body, a new hollow-core optical waveguide based on Photonic Crystal Fiber (PCF) is proposed and numerically studied. The refractive index (RI) differs between normal and cancerous cells, and it is through this distinction that the other crucial optical parameters are assessed. The proposed cancer cell biosensor’s guiding characteristics are examined in the COMSOL Multiphysics v5.5 environment. The Finite Element Method (FEM) framework is used to quantify the display of the suggested fiber biosensor. Extremely fine mesh elements are additionally added to guarantee the highest simulation accuracy. The simulation results on the suggested sensor model achieve a very high relative sensitivity of 99.9277%, 99.9243%, 99.9302%, 99.9314%, 99.9257% and 99.9169%, a low effective material loss of 8.55×10−5 cm−1, 8.96×10−5 cm−1, 8.24×10−5 cm−1, 8.09×10−5 cm−1, 8.79×10−5 cm−1, and 9.88×10−5 cm−1 for adrenal gland cancer, blood cancer, breast cancer type-1, breast cancer type-2, cervical cancer, and skin cancer, respectively, at a 3.0 THz frequency regime. A very low confinement loss of 6.1×10−10 dB/cm is also indicated by the simulation findings for all of the cancer cases that were mentioned. The straightforward PCF structure of the proposed biosensor offers a high likelihood of implementation when used in conjunction with these conventional performance indexes. So, it appears that this biosensor will create new opportunities for the identification and diagnosis of various cancer cells.

“…And Abutan et al presented a hollow core PCF sensor for gas sensing [10]. For the detection of organic compounds in aqueous solution, optical fiber sensor also has great potential and has been used to detect formaldehyde, ethanol, and benzene, etc [11,12]. For glycerol detection, there are already some fiber detectors based on surface plasmon resonance (SPR).…”

In this paper, we design and theoretically simulate a highly sensitive photonic crystal fiber sensor based on lossy mode resonance. An ITO/HfO 2 bilayer was coated onto the exposed area of the fiber core as the sensing material. This asymmetrical structure can lead both TM-and TE-polarization to improve the detection performance. In addition, we further investigated the influence of the ratio of ITO/HfO 2 bilayer film thickness on the maximum sensitivity of the proposed sensor and finally reached a maximum sensitivity at 1.92nm/1% for glycerol solutions detection, which plays a significant role in the optical fiber sensor in the field of glycerol detection.
