Nonlinear-optical frequency-doubling meta-reflector: pulsed regime

TL;DR

This paper investigates a nonlinear-optical frequency-doubling meta-reflector operating in pulsed regimes, revealing how the pulse length to metaslab thickness ratio influences its unique operational properties, differing from conventional second harmonic generation.

Contribution

It introduces a novel analysis of backward-wave second harmonic meta-reflectors in pulse regimes, highlighting the impact of pulse length to metaslab thickness ratio on their behavior.

Findings

Operational properties depend on pulse length to metaslab thickness ratio.

Distinct behavior from traditional second harmonic generation.

Potential for tailored nonlinear optical devices.

Abstract

The properties of backward-wave second harmonic meta-reflector operating in pulse regime are investigated. We show that ratio of the income pulse length to the thickness of the metaslab determines its important operational properties which are in contrast with those manifested at common second harmonic generation settings.
