“…The proposed biosensor is analyzed for glucose biomolecules detection with its concentrations, refractive indexes, and results are presented in Figure 2. The refractive index increases with an increase in glucose concentrations as presented in Figure 2C 17 . The biosensor design shown in Figure 1 is simulated using COMSOL Multiphysics using periodic boundary conditions.…”

This study aims to design a metamaterial sensor to detect glucose levels in the human body so that the severity of diabetic patients can be determined.The biomolecules are placed over gold metamaterial to observe the behavior of the sensor. The proposed model is analyzed for both phases of GST (amorphous GST [aGST] phase and crystalline GST [cGST] phase). The design is analyzed for parameters like absorption, angle of incidence of light, the concentration of glucose biomolecules, substrate, tuning of the wavelength spectrum, and resonator thickness. The sensor with cGST provides better performance. Observing angle of incidence, 95% absorption is noticed with 48-60°radians for wavelength range 0.85-0.98 μm and with 42-69°radians for wavelength range 0.85-0.98 μm. The analysis depicts that the proposed phase change material-based biosensor in general and with cGST, in particular, is suitable for glucose detection in the blood of diabetic patients.

“…In addition, based on the detection principle of a PhC resonator and waveguide-based optical sensor, several applications, such as environmental monitoring [ 32 ] and food control [ 33 ], can be performed to extend the PhC resonator and waveguide’s use beyond medical applications. For these applications, volatile organic compounds (VOCs) and toxic substances can be detected by using the PhC resonator and waveguide.…”

In this paper, we have proposed a polymer-based photonic crystal (PhC) resonator, with multiple sizes of cavities, and a waveguide to be used as highly sensitive optical sensor components. Properties of the proposed PhC were simulated by the finite-difference time-domain method, and the polymer-based PhC resonator and waveguide were fabricated on a photoresist (polymer) by electron beam lithography, which was prepared on an Au-layer-deposited Si substrate. We detected the resonant light that penetrated through the waveguide and was trapped in the PhC resonator. Optical characteristics of the fabricated PhC were evaluated by detecting the polymer layer deposition process by using the layer-by-layer (LbL) method to deposit polymer layers. As a result, by using an optimized design of a polymer-based PhC resonator with a long cavity (equivalent to a defect of three holes), the PhC structure changes caused by LbL deposition lead to changes in resonant light wavelength (peak shift: 5.26 nm/layer). Therefore, we suggest that a PhC resonator and a waveguide is applicable as an optical sensor.

“…The peak wavelength of the respective emission spectra was used to calculated the applied grating periods using Equation ( 1 ) with the consideration that the refractive index of PMMA was 1.49. According to Malinin, A. et al [ 49 ], the theoretical value of the refractive index of the sugar concentration (

) can be calculated using the equation below:

where,

or wt%. The experimental value of the refractive index of sugar solution was accomplished by using the refractometric method.…”

Organic thin-film lasers gain interest as potential light sources for application in diverse fields. With the current development, they hold variety of benefits such as: low-cost, high-performance, and color-tunability. Meanwhile, the production is not complicated because both the resonator and the gain medium can be assembled by solution-processable organic materials. To our knowledge, information about using poly(methyl methacrylate) (PMMA) as a matrix for organic dye lasers was insubstantial. Herein, the feasibility of using organic dye-doped PMMA as an organic dye laser was tested. Six different sample designs were introduced to find out the best sample model. The most optimum result was displayed by the sample design, in which the gain medium was sandwiched between the substrate and the photoresist layer with grating structure. The impact of dye concentration and grating period on peak wavelength was also investigated, which resulted in a shift of 6 nm and 25 nm, respectively. Moreover, there were in total six various organic dyes that could function well with PMMA to collectively perform as ’organic dye lasers’, and they emitted in the range of 572 nm to 609 nm. Besides, one of the samples was used as a sensor platform. For instance, it was used to detect the concentration of sugar solutions.
