Abstract

We experimentally demonstrate a self-coherent freespace optical communications (FSOC) system based on the pilot-assisted scheme. By co-propagating the data-carrying beam with a continuous-wave pilot, the scheme reduces turbulenceinduced losses in spatial coherence between the beams, which can adversely affect the performance of local oscillator (LO)- based coherent systems. The system utilizes a single free-space photodetector and self-coherent detection based on the Kramers- Kronig receiver to minimize receiver hardware complexity. Using an 800 m free-space link, we transmit a 10 Gbit/s 16-QAM single polarization signal over real atmospheric turbulence. Additionally, we present a method for simultaneous characterization of the atmospheric channel by recording image sequences of the received laser spot. Results demonstrate the robustness of the system in moderate turbulence, and serve as the first field demonstration of this approach over a real free-space link.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
