Harmonic generation in silicon nitride ring resonators

Harmonic generation in silicon nitride ring resonators.

We demonstrate second- and third-harmonic generation in a centrosymmetric CMOS-compatible material using ring resonators and integrated optical waveguides. The χ(2) response is induced by using the nanoscale structure of the waveguide to break the bulk symmetry of silicon nitride (Si3N4) with the silicon dioxide (SiO2) cladding. Using a high-Q ring resonator cavity to enhance the efficiency of ...

Second-harmonic generation from complementary split-ring resonators.

We present experiments on second-harmonic generation from arrays of magnetic split-ring resonators and arrays of complementary split-ring resonators. In both cases, the fundamental resonance is excited by the incident femtosecond laser pulses under normal incidence, leading to comparably strong second-harmonic signals. These findings are discussed in terms of Babinet's principle and in terms of...

Backscattering Effects In Silicon Ring Resonators

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;
