Light Guide Film Control for Optically Tunable Metamaterials

摘要

A metamaterial control device is provided for controlling electromagnetic radiation. The device uses a light-guide film (LGF), with the LGF being capable of receiving light emission along an edge. The device includes a substrate disposed on a non-edges surface of the LGF, electromagnetic cellular structures that are controllable, and an optically sensitive component within some or all cells. The substrate is composed of metamaterial and having an interface that corresponds to an extractor on the non-edge surface for scattering light therefrom. Alternatively, the substrate can constitute the LGF itself. The cell structure is disposed around the extractor. The optically sensitive component is disposed to cover the extractor. The component changes in response to receiving the light from the extractor and changes in response to intensity of the light.

1. A metamaterial control device for controlling electromagnetic radiation, said device receiving light emission, said device comprising:
a light-guide film (LGF) substrate for receiving the light emission, said substrate being composed of metamaterial and having an extractor on a non-edge surface of the LGF, said extractor scattering light therefrom; an electromagnetic cell structure disposed on said substrate around said extractor, said cell structure having first and second characteristics depending on intensity said scattered light from said extractor; and an optically sensitive component disposed to cover said extractor and provide said scattered light to said cell structure, wherein said cell structure shifts from said first characteristic to said second characteristic in response to receiving said scattered light from said component.
