Summary

This summary is machine-generated.

We achieved phase-matched second-harmonic generation (SHG) in 3D metamaterials by engineering stacked metasurfaces. This novel backward SHG signal scaled superlinearly with the number of layers, paving the way for efficient nonlinear optics.

Area of Science:

Photonics and optical engineering
Materials science
Nonlinear optics

Background:

Phase-matched second-harmonic generation (SHG) is crucial for nonlinear optical devices.
Achieving phase matching in three-dimensional (3D) metamaterials presents significant challenges.
Conventional SHG often occurs in the forward direction, limiting applications.

Purpose of the Study:

To demonstrate phase-matched SHG from 3D metamaterials composed of stacked metasurfaces.
To explore a novel phase engineering approach for achieving backward SHG.
To investigate the scalability of SHG signal with the number of stacked metasurfaces.

Main Methods:

Fabrication of three-dimensional metamaterials using stacked metasurfaces.
Phase engineering of metasurfaces at interacting wavelengths to control phase matching.
Experimental measurement of second-harmonic generation signal in the backward direction.

Main Results:

Successfully demonstrated phase-matched second-harmonic generation (SHG) in stacked 3D metamaterials.
Utilized a novel phase engineering mechanism to achieve SHG in the backward direction.
Observed a superlinear scaling of the phase-matched SHG signal with an increasing number of metasurface layers (up to five).

Conclusions:

The study successfully demonstrates phase-matched backward SHG in 3D metamaterials.
Phase engineering of stacked metasurfaces is a viable strategy for controlling nonlinear optical processes.
The superlinear scaling indicates potential for enhanced nonlinear efficiencies with more complex structures.
