US 2016/0261086 A1 · TUNABLE LIGHT MODULATION USING GRAPHENE

Abstract

Described herein are optical devices based on two-dimensional materials and methods for making such devices. In particular, the articles described herein are useful in the control and modulation of light via graphene mono- or multilayers. methods for improved transfer of graphene from formation substrates to target substrates. The improved articles provide exceedingly high modulation depths in vis-NIR light transmission, with small insertion losses, thus revealing the potential of graphene for fast electro-optics within such a technologically important range of optical frequencies.

Dependent claims

An optical modulating device comprising:

(a) a resonating optical structure in which the light intensity of an optical beam is amplified;
and
(b) an ultrathin layer inside or in proximity of the aforesaid resonating structure operating in the linear optical regime, whereby the modulation of the light transmitted, reflected or generated by the resonating structure is achieved by applying an electrical voltage, EF, or mechanical displacement to the ultrathin layer.

Dependencies are inferred from the claim text.
