Second harmonic generation in amorphous silicon-on-silica metamaterial

Second harmonic generation in amorphous silicon-on-silica metamaterial

We demonstrate second harmonic generation by using an amorphous silicon metamaterial fabricated on the tip of an optical fiber 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 −1, which exceeds the previously achieved value for a silicon metamaterial by two orders of magnitude.

Abstract

We demonstrate second harmonic generation by using an amorphous silicon metamaterial fabricated on the tip of an optical fiber 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 −1, which exceeds the previously achieved value for a silicon metamaterial by two orders of magnitude.
