OPTICAL DATA TRANSFER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18636249 titled 'OPTICAL DATA TRANSFER
Simplified Explanation: The patent application describes a system where a beam modulator embeds data into an input beam, which is then guided through a multimode optical waveguide network. A spatial coherent detector measures the output optical field to compensate for distortion effects caused by the waveguide, allowing for the recovery of the embedded data.
- **Beam modulator embeds data into input beam**

Original Abstract Submitted
In an optical data transfer system, a beam modulator is configured to embed a set of data in an input beam. A multimode optical waveguide network has an in-coupling region for receiving the input beam. The multimode optical waveguide network is configured to guide the input beam to an out-coupling region of the multimode optical waveguide network. A spatial coherent detector is configured to measure a phase and an amplitude of an output optical field at multiple locations. The output optical field is at least partially defined by the input beam and thus exhibiting distortion effects caused by the passage of the beam through the multimode waveguide network. Signal processing is applied to an output of the spatial coherent detector, in order to compensate for the distortion effects, and thereby recover, from the output of the spatial coherent detector, the set of data embedded in the input beam.
