METAMATERIAL STRUCTURES FOR Q-SWITCHING IN LASERS

摘要

Techniques described herein are generally related to metamaterial structures for Q-switching in laser systems. The various described techniques may be applied to methods, systems, devices or combinations thereof. Sonic described metamaterial structures may include a substrate and a first conductive layer disposed on a first surface of the substrate. A dielectric layer may be disposed on a first surface of the first conductive layer and a second conductive layer having a substantially symmetric geometric shape may be disposed on a first surface of the dielectric layer. The second conductive layer may cover a portion of the first surface of the dielectric layer.

1. A metamaterial structure, comprising:
a substrate; a first conductive layer disposed on a first surface of the substrate; a dielectric layer disposed on a first surface of the first conductive layer, wherein the dielectric layer is configured to undergo a phase change with a change in temperature from an absorptive state to a reflective state at a transition temperature of the dielectric layer in response to heat generated by absorption of infrared radiation by the metamaterial structure; and a second conductive layer disposed on a first surface of the dielectric layer, wherein the second conductive layer covers at least a portion of the first surface of the dielectric layer, and wherein the second conductive layer has a substantially symmetric geometric shape.
