Second-harmonic generation from complementary split-ring resonators

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...

A Compact Ultra-Wideband Bandpass Filter with Sharp-Rejection using Complementary Split Ring Resonators

A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...

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 ...

A Microstrip Highpass Filter with Complementary Split Ring Resonators

An accurate equivalent circuit model for the microstrip line with a complementary split ring resonator (CSRR), and the parameter extraction method, are presented. A highpass filter with steep rejection is designed based on the model. The measurement results confirm the efficient analysis and design procedure and the validity of the highpass filter configuration. DOI: 10.2529/PIERS060906062902
