“…This effect is reflected as a shift in the resonant wavelength in the measured spectrum. The ring resonator is an exceptional optical sensor because of its higher Q value, high sensitivity, ease of fabrication, multiplexity capability, and label-free detection [40]. During operation, the ring resonator is immersed in the running buffer that flows stably in the microfluidic channel, and a stable resonant peak is observed.…”

The angular properties of sensor, implemented in Kretschmann’s scheme, where the optimized for oblique incidence of light thin-film reflection interferometer acts as a sensing element, are described in the paper. Analytical equations, defining the sensor’s properties for S and P polarization states at working wavelength in vicinity of working angle of incidence, are provided, as well as approximate equations for main parameters of sensor: sensitivity, angular full width at half maximum, contrast and figure of merit. The possibility to vary the named parameters by choosing appropriate metal and dielectric layers of the structure is shown. For an example, the numerical calculations are made for one of special cases, optimized for S polarization state, as having larger figures of merit. The dependencies of angular properties on number of layers and base thickness are demonstrated. It is shown, that angular measurements with this method are theoretically capable of infinite figures of merit, and in practice they are only limited by losses in layered structure and beam divergency. The recommendations for experimental realization of method are given.

“…Silicon is the material of choice to fabricate MRRs, as advanced silicon technology, especially in electronic industries, has made it possible to design MRRs at a relatively low cost [6]. Recent developments in the field of MRRs have led to a renewed interest in optical sensing applications, especially in the biomedical field [7]. It has been reported that MRRs have the ability to produce an integrated sensing device with high sensitivity that allows detection of ultra-low molecule concentration [8,9].…”

The properties of light and its interaction with biological analytes have made it possible to design sophisticated and reliable optical-based biomedical sensors. In this paper, we report the simulation, design, and fabrication of microring resonator (MRR)-based sensors for the detection of diabetic glucose levels. Electron Beam Lithography (EBL) with 1:1 hydrogen silsesquioxane (HSQ) negative tone resist were used to fabricate MRR on a Silicon-on-Insulator (SOI) platform. Scanning Electron Microscopy (SEM) was then used to characterize the morphology of the MRR device. The full-width at half-maximum (FWHM) and quality factors of MRR were obtained by using a tunable laser source (TLS) and optical spectrum analyzer (OSA). In this paper, the three-dimensional Finite Difference Time Domain (3D FDTD) approach has been used to simulate the proposed design. The simulation results show an accurate approximation with the experimental results. Next, the sensitivity of MRR-based sensors to detect glucose levels is obtained. The sensitivity value for glucose level detection in the range 0% to 18% is 69.44 nm/RIU. This proved that our MRR design has a great potential as a sensor to detect diabetic glucose levels.
