Reconfigurable interference

Abstract

Aspects of the present disclosure are directed to a reconfigurable interference device comprising a phase change structure. The phase change structure comprises a solid-state phase change material having a first phase state and a second phase state dependent on temperature. A first energy source is configured to supply an initialization energy to initialize a plurality of domains having the first phase state and a second energy source is configured to supply an electrical current to the structure to position the plurality of domains of the first phase state within the phase change structure. A control unit is configured to control the first and the second energy source and to create a periodic interference pattern comprising a plurality of domains of the first phase state and a plurality of domains of the second phase state in an alternating pattern.

Dependencies are inferred from the claim text.
