HIGH-FREQUENCY OPTICAL SWITCH AND ITS MANUFACTURING METHODS Russian patent published in 2022 - IPC G02F1/19 

FIELD: optics.

SUBSTANCE: invention relates to the field of optical switches. An optical modulator contains optically transmitting substrate made with the possibility of distribution of electromagnetic radiation through it, and a metamaterial structure optically connected to the specified substrate. The metamaterial structure contains at least one layer of metamaterial particles, optically connected to at least some part of the specified optically transmitting substrate, and at least one nano-mesh layer made of at least one electroconductive material placed above at least some part of one metamaterial layer. At least one nano-mesh layer is made with the possibility of discharge of electrons to the specified at least one metamaterial layer, which is made with the possibility of transition from an optically non-transparent state to an optically transparent state, when receiving discharged electrons, while at least partially changing electromagnetic radiation passing through substrate.

EFFECT: invention provides optical modulation of long waves in a terahertz range.
