Non-volatile dielectric metamaterials reconfigurable with light

Non-volatile dielectric metamaterials reconfigurable with light
In this work we combine the concepts of low-loss dielectric metamaterials, phase-change media and femtosecond-laser writing to produce a novel technology for manufacturing rewritable metamaterials and optical devices with advanced functionalities. By shining spatially- and temporally-engineered femtosecond laser pulses onto a phase-change nano-film, we can write arbitrary grayscale patterns into the film. These patterns are used to create metamaterials and other complex optical devices.

Abstract

In this work we combine the concepts of low-loss dielectric metamaterials, phase-change media and femtosecond-laser writing to produce a novel technology for manufacturing rewritable metamaterials and optical devices with advanced functionalities. By shining spatially- and temporally-engineered femtosecond laser pulses onto a phase-change nano-film, we can write arbitrary grayscale patterns into the film. These patterns are used to create metamaterials and other complex optical devices.
