Invention:
This technology relates to a combination of an entanglement-assisted free-space optical communication testbed and orbital angular momentum (OAM)-based beam shaping to acquire and communicate with receivers whose exact position is unknown, covering a wide search area in strong turbulence regime.
Background:
Establishing a free-space optical (FSO) communication link between communicating parties becomes difficult when the transmitter does not know the precise location of the receiver. While many current methods entail locating the target and determining its position, this technology offers a novel approach that uses orbital angular momentum (OAM) beams to obtain the target in order to establish communication.
Applications:
- Quantum communications
- Wide-range free-space optical (FSO) communications
Advantages:
- Compatible for a receiver of unknown position
- Covers wider area in strong turbulence regime
- Lower latency
