Claim Text:
1. An electro-optical sampling device for electro-optical sampling of a microwave frequency signal comprising: a microwave transmission line configured to transmit a microwave signal, the microwave transmission line comprising an interruption zone configured to be rendered conducting under the effect of an optical control signal so as to carry out a function of optically controlled interrupter switch, wherein the device further comprises, in the interruption zone, a layer of nanostructured semiconductor material comprising a periodic or quasi-periodic tiling of nanostructures, the semiconductor material having a refractive index, the layer of nanostructured semiconductor material being placed, at the level of the interruption zone, in suspension or on a dielectric material of lower refractive index than the refractive index of the semiconductor material, the layer of nanostructured semiconductor material configured to carry out the function of optically controlled interrupter switch.
