Modeling and Characterization of Active Silicon Microring Resonators — •Kambiz Jamshidi, Abdou Shetewy, and Menglong He — Integrated Photonics Devices Group, Chair of RF and Photonics, Technische Universität Dresden, 01069, Dresden, Germany

Silicon ring resonators can be used for several applications in communication, signal processing, and computing. By embedding the silicon waveguide in a pn junction, it is possible to tune the free carrier lifetime of the waveguide, which provides an additional degree of freedom to tune the steady-state response of these resonators and therefore the regime in which they operate. A theoretical framework is required to model the dynamics of light evolution in these resonators, taking into account the number of free carriers in the resonator and its temperature. In this article, the nonlinear coupled equations required for this modeling will be reviewed. In addition, characterization results of the resonators, which are fabricated in a standard process using silicon-on-insulator technology, will be discussed. Finally, several applications of the resonators at different biases will also be presented.
