This study proposes a simple and efficient Photonic Crystal Fibre sensor design for the detection of controlled drugs such as cocaine, amphetamine, and ketamine. The design uses a pentagonal core hole and circular cladding air holes in 2 layers, made of fused silica substrate. The sensing performance of the proposed PCF design is evaluated using COMSOL Multiphysics and Finite Element Method, operating in the visible and infrared range from 0.4 to 3.2 μm. Results show that the proposed PCF design achieves high relative sensitivities of 99.55%, 99.75%, and 99.99% for cocaine, amphetamine, and ketamine, respectively, at the optimum wavelength of 0.4 μm. Additionally, the design is robust, showcasing minimal variations in relative sensitivities with changes in pitch distance, air hole diameter, and core hole length. These findings make the proposed PCF design a promising candidate for practical controlled drug sensing.

An elliptical core-based D-shape photonic crystal fiber (PCF) has been proposed with achieving extraordinary optical properties in this paper. We deeply observed and evaluated the performance of the designed D-PCF by doping the materials (As 2 S 3 and As 2 S 5 ) separately into the core region with the variation of the eccentricities (core size). After the whole analysis, this D-PCF prefers the As 2 S 3 core material because it produces a better performance of all the optical features compared to the As 2 S 5 material. The results of the raised PCF shows that the maximum nonlinearity of 9.114×10 4 W −1 km −1 , the extreme-high birefringence of 0.254, the better power fraction of 99.51%, the high numerical aperture of 0.78, the large negative dispersion of −2560.12 ps/(nm-km), and the low beat length of 7.09 μm, etc. The finite element method (FEM) has been applied to simulate the optical characteristics and a perfectly matched layer (PML) is used as a boundary condition. So, the above mentioned remarkable outcomes of the designed D-PCF makes it a robust candidate in many helpful applications like biomedical imaging, telecom, super-continuum generation, and polarization-maintaining signal processing.

The third-order optical nonlinearities of methyl green in aqueous solution are studied by the Z-scan technique using a femtosecond laser at 800 nm. The valley shape in the open aperture measurements reveals the presence of reverse saturable absorption effect, which is ascribed to the three-photon absorption process. The closed aperture Z-scan traces demonstrate a negative sign for the nonlinear refractive coefficient, indicating the self-defocusing optical nonlinearity. Furthermore, the magnitudes of the nonlinear refractive index n 2, the three-photon absorption coefficient α 3, and the real part of the third-order nonlinear optical susceptibility Re χ (3) are determined and found to be linearly proportional to the dye concentration within the investigated range. Our results suggest that methyl green may be a hopeful candidate for applications in nonlinear optics.
