A comparative study on characteristics and performance of optical ring resonator architectures, i.e. circular, racetrack, and triangular-shaped optical resonators, have been carried out here. Constituent material used for designing these resonators is an silicon on insulator wafer consisting of thin silicon (Si) layer on silica (SiO 2) layer carried on a thick Si substrate having group index of 2.379. All the resonators are so designed that all provide equal free spectral range (FSR) of 25.2 THz. All these double-ring architectures have been analysed using delay line signal processing technique in z-domain and Mason's gain formula. FSR expansion has been achieved employing the Vernier principle. Various performance defining parameters have been also investigated.

“…Racetrack and ring microresonators are essential elements of the existing integrated optics platforms [1]. They permit to implement add-drop multiplexers [2], optical filters [3,4], optical switches [5], sensors [6], modulators [7], and they are the building blocks of slow and fast light systems based on coupled resonator waveguides [8,9].…”

A numerical study of the radiation in coupled bent waveguides is presented. Such arrangements of curved waveguides in reduced radiation-loss configurations can be used to enhance the quality factor of integrated micro-resonators. 3D full vector computations of the complex modal fields (and propagation constants) and the transient propagation effects have been performed. The results obtained agree qualitatively with former 2D FDTD analyses. At the same time, the calculations presented meet the accuracy requirements for the design of practical implementations that are unattainable with 2D approaches.

“…Microring devices have reached a prominent status as a key technology for the implementation of both linear [1], [2], [3], [4], [5], [6] and nonlinear [7], [8] photonic signal processing functionalities. In particular, due to their versatility, coupled resonator optical waveguides (CROW) [9] find many applications in the control of the group delay [10], [11].…”

Abstract-The longitudinal offset technique permits to improve the accuracy of the coupling coefficients of integrated directional couplers and provides designs that can be easily implemented with current fabrication tolerances. In this work, we address the additional degree of freedom offered by this technology in order to tailor the differential group delay in coupled-resonator optical filters. We present the characterization of several devices exploiting this feature and we discuss their potential applications.
