“…Although the Vernier effect was used in other applications such as optical filters [11,12] and tunable lasers [13,14], it was only recently proposed for sensor application [15]. By using the Vernier effect we can increase the sensitivity of the effective refractive index measurement without requiring a narrow line width tunable laser or a high-resolution OSA.…”

“…Nowadays, various configurations of ring resonators have been proposed, such as single-ring resonators [1,2], series-coupled resonators [3], parallel-coupled resonators [4,5], and many other complicated structures [6,7]. Scale of rings in these resonators can be chosen from decimeters of fiber rings to microns of waveguide rings.…”

The transmission characteristics of the nested ring resonator are analyzed. The intensity transmission of the resonator is obtained. Based on this, the critical coupling and coupled-resonator-induced transparency conditions are derived as length ratio of the U-shaped loop and the inner circle ring is an integer or half-integer. Accurate expressions of these two conditions are provided. Numerical calculation at some specific parameters verifies the conditions and demonstrates their variations vs. parameters of the resonator.

“…The scattering parameters of a variety of the optical devices can be significantly improved by using microresonators of different forms [2][3][4][5][6]. In the early works, for the theory simplification, all microresonators are generally supposed to have the same shape and manufactured of the same dielectric.…”

Background. At the present time, further increase in the speed of processing and transmission of information is associated with the development of hybrid integrated circuits, combining electrical and optical components. One of the important constituent parts of future optical integrated circuits are filters that can be conveniently implemented using so-called disc microresonators with whispering gallery oscillations.Technically, the problem of manufacturing such filters in the infrared and even in the visible wavelength range has been solved, but calculation of parameters and tuning of multilink filters is impossible without further development of the theory of their building. The development of such a theory is based on the electrodynamic modeling of processes that occur in complex systems of coupled microcavities, coupled also with transmission line. At present, the study of filters built on different microresonators has not been carried out.Objective. The aim of the research is to construct the theory of scattering of electromagnetic waves of the integral optical transmission lines on systems of coupled different optical microresonators with whispering gallery modes.Development of mathematical models of filters constructed using various disk microresonators. Investigation of new structures of coupled microresonators with acceptable scattering characteristics.Methods. To construct a mathematical model of filters, an approximate solution of the Maxwell equations based on perturbation theory is used. The application of perturbation theory made it possible to find a solution to the problem of calculating the S-matrix of the filter in an analytical form.Results. An electrodynamic model for the scattering of optical transmission line waves by a system of different shapes coupled microresonators and made of different dielectrics is developed. New structures of microresonators, realizing bandpass and bandstop filters, are investigated and their scattering characteristics are calculated.Conclusions. The theory of scattering of electromagnetic waves by systems of various coupled optical microresonators is expanded. A new definition of the coupling coefficients of different microresonators is given. New models of filters are constructed.
