Abstract
This disclosure provides a waveguide including a sequence of variable transparency segments, wherein each variable transparency segment of the sequence of variable transparency segments is configured to vary its transparency by the electromagnetically Induced Transparency (EIT) effect and further vary its transparency in response to an incident electromagnetic field; and a plurality of separator segments interspersed within the sequence of variable transparency segments so that each variable transparency segment: has a first separation distance from a first other variable transparency segment being a first predetermined number of variable transparency segments preceding or succeeding in the sequence of variable transparency segments, has a second separation distance from a second other variable transparency segment being a second predetermined number of variable transparency segments preceding or succeeding in the sequence of variable transparency segments, and is uniquely identified by a combination of separation distances comprising its first and second separation distances.
