Second harmonic generation in amorphous silicon-on-silica metamaterial

Second harmonic generation in amorphous silicon-on-silica metamaterial
Second harmonic generation in amorphous silicon-on-silica metamaterial
We demonstrate second harmonic generation by an amorphous silicon metamaterial fabricated on the tip of an optical fibre that collects the generated light. The metamaterial is a double chevron array that supports a closed-mode resonance for the fundamental wavelength at 1510 nm with a quality factor of 30. The normalized resonant second harmonic conversion efficiency calculated per intensity and square of interaction length is ~10-11/W which exceeds the previously achieved value for silicon metamaterial by two orders of magnitude.

Abstract

We demonstrate second harmonic generation by an amorphous silicon metamaterial fabricated on the tip of an optical fibre that collects the generated light. The metamaterial is a double chevron array that supports a closed-mode resonance for the fundamental wavelength at 1510 nm with a quality factor of 30. The normalized resonant second harmonic conversion efficiency calculated per intensity and square of interaction length is ~10-11/W which exceeds the previously achieved value for silicon metamaterial by two orders of magnitude.
