“…Due to its high quality factor and low loss, the micro ring resonator (MRR) based on SOI is used to produce various optical devices, such as filters [3], optical division multiplexer [4], optical switch [5], sensor [6], etc., which has a wide range of applications in environmental monitoring, homeland security, biochemistry and medical treatment [7,8].Because the transmission lines of traditional micro ring resonators are symmetrical Lorentz type [9], the quality factor and sensitivity are low. By designing a new structure, the transmission line can be changed from Lorentz type to Fano type, or the EIT-Like effect can be generated to improve the quality factor, extinction ratio (ER) and sensitivity of the micro ring resonator [10]. Therefore, researchers have designed many new structures.…”

In this paper, a micro ring resonator with slit structure of three-ring grating is proposed to make the refractive index micro ring sensor have higher quality factor and sensitivity. Based on the traditional micro ring resonator, the structure adopts three micro rings and adds grating structure to the rings, which can realize the EIT-Like effect at different wavelengths. Furthermore, the quality factor and sensitivity of the micro ring resonator are improved. The structure is simulated using the finite difference time-domain (FDTD) technique and the influence of device parameters on the structure is investigated. Quality factor was found to be up to 24845, over threefold higher than conventional microring sensors. The sensitivity is 224.2nm/RIU, more than two times higher than the conventional micro ring refractive index.

“…The series multiring structure can expand the free spectral range by combining multiple microrings with different radii to optimize the filtering function performance. Therefore, researchers have extensively researched microring resonators with series structures such as double‐ring [17], three‐ring [18], and four‐ring [19]. The three‐ring structure has a more extensive free spectral range than the double‐ring structure, and it is easy to suppress the pseudo‐mode characteristics, dramatically increasing the microring sensor's performance.…”

In this paper, a high-sensitivity refractive index sensor based on a hybrid plasma waveguide and metal-insulator-metal waveguide combined third-order runway series mosaic microring resonator is proposed. In this structure, a GaAs waveguide ring surrounds a gold waveguide ring in the middle, and the innermost layer is a disk made of gold material.The outer groove waveguide is composed of GaAs-air-alloy, and the inner groove waveguide is made of the Gold-Air-Gold material disc. By filling different substances in the groove, the change of refractive index will affect the optical signal strength of the output spectrum. The finite element method simulates the transmission spectrum and electric field distribution of the sensor structure. The amplitude coupling coefficient and attenuation factor affecting the resonator's performance are analyzed, and the structural parameters of the slot waveguide are optimized. The numerical simulation results show that the sensor quality factor of this structure is 1.54 Â 10 4 , the sensitivity is 1.2 Â 10 3 nm/RIU which is about 1.5 times higher than that of the Si ring with the same structure, the detection limit can reach 8.1892 Â 10 À7 RIU, and the free spectral range can reach 109 nm. Compared with the traditional microring structure, this microring has higher design freedom and free spectral range and is more suitable for producing biosensors with high sensitivity, low detection limit, and multi-parameter measurement.
