چکیده

Backscattering can dramatically modify the response of ring resonators and be the limiting parameter of the Q-factor. We present evidence of backscattering, a model, and a fitting procedure that provides a complete characterization of the resonance. Keywords—resonators; backscattering;

Backscattering in Silicon Microring Resonators: A Quantitative Analysis

Silicon microring resonators very often exhibit resonance splitting due to backscattering. This effect is hard to model in a quantitative and predictive way. This paper presents a behavioral circuit model for ring resonators that quantitatively explains the wide variations in resonance splitting observed in experiments. The model is based on an in-depth analysis of the contributions to backscat...

Characterizing and modeling backscattering in silicon microring resonators.

We present an experimental technique to characterize backscattering in silicon microring resonators, together with a simple analytical model that reproduces the experimental results. The model can extract all the key parameters of an add-drop-type resonator, which are the loss, both coupling coefficients and backscattering. We show that the backscattering effect strongly affects the resonance s...

Nonlinear Modeling and Investigating the Nonlinear Effects on Frequency Response of Silicon Bulk-mode Ring Resonator

This paper presents a nonlinear analytical model for micromechanical silicon ring resonators with bulk-mode vibrations. A distributed element model has been developed to describe the dynamic behavior of the micromechanical ring resonator. This model shows the nonlinear effects in a silicon ring resonator focusing on the effect of large amplitudes around the resonance frequency, material and ele...

Backscattering in silicon photonic devices

We report on the backscattering induced by sidewall roughness in silicon on insulator optical nanowires, its dependence on the waveguide geometrical and optical parameters and its impact on silicon photonic devices. In silicon ring resonators cavity-enhanced backscattering, increasing with the square of the resonator’s finesse, emerges as a severe
