“…An integer multiple of unit delay is consider as total delay of filter. To demonstration, the z-transform of a discrete time signal f (z) is (Ranjan et al 2016 ), where z-transformed unit delay is z − n . Triple unsymmetrical micro ring resonator arrangements have four directional couplers that are drawn with a delay line signal processing method.…”

Representation of triple unsymmetrical micro ring resonators (TUMRR) with single input and single output waveguide has been executed in this paper. Statistical demonstration of the presented arrangement is realized in the z-domain by a delay line signal processing method. The transfer function of the triple unsymmetrical micro ring resonator is calculated by Mason’s Gain rule. The offered arrangement is performed on SOI (Silicon in Insulator) platform to achieve the filtering and biochemical sensing intentions. To acquire field response of the arrangement, Finite difference time domain (FDTD) technique is used. Characteristics of optical filters are studied from the frequency response plot and the achieved free spectral range is 243.5 GHz. The shift in wavelength for biosensing application is accomplished through the OptiFDTD software. The sensitivity of the proposed TUMRR based biosensor is around 200–280 nm/RIU for different blood cells where as the Q-factor attained is 1938.

“…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.
