SatEnlight provides free‑space optical communication links that use orbital angular momentum (OAM) spatial multiplexing to transmit multiple independent data streams over a single laser beam. Their patented low‑complexity receiver demultiplexes these OAM channels and includes turbulence‑mitigation electronics, delivering higher capacity, built‑in physical‑layer security, and compatibility with existing Gaussian‑beam terminals for satellite and ground‑station operators.

Problem
Satellite constellations generate massive data volumes, but existing radio‑frequency links are nearing spectral saturation, offering limited bandwidth, high interference, and security constraints. Free‑space optical links provide higher carrier frequencies, yet most systems transmit data using only a single spatial mode, restricting capacity growth.
Solution
SatEnlight introduces spatial multiplexing using Orbital Angular Momentum (OAM) to encode multiple independent data streams within a single optical beam. Their patented multi‑aperture receiver samples a localized region of the incoming wavefront, allowing simultaneous demultiplexing of several OAM channels without full wavefront reconstruction. The system includes a turbulence‑mitigation module that compensates atmospheric phase distortions, preserving link reliability. By leveraging OAM, SatEnlight multiplies channel capacity, enhances physical‑layer security—since OAM states cannot be decoded without the specialized receiver—and can be integrated with existing Gaussian‑beam terminals, enabling a scalable upgrade path for current optical communication infrastructure.
Target Audience
Primary customers are satellite operators and space‑based communication providers seeking high‑capacity, secure free‑space optical links, as well as ground‑station manufacturers integrating advanced optical terminals into their platforms.
