Space Photonics Receives Patent for Free Space Laser Communications

Facebook Twitter LinkedIn Email
Space-qualified optics developer Space Photonics Inc. has received its seventh patent in the technology sector that includes free space laser communications.

The new patent, titled “Simultaneous Multi-Channel Optical Communications System with Beam Pointing, Switching and Tracking Using Moving Focal Plane Devices,” and the company’s other patents, use specific inventions for very rapid and extremely accurate angular pointing and tracking of free space laser communications beams used for ultrahigh-capacity digital signals commonly used in ground-based internet networks. The technology will provide a much needed boost for emerging global networks using satellites, aircraft and high-altitude balloons.

“This patent is by far the most valuable we’ve received. It provides innovative but simple techniques for pointing and tracking laser communications beams sent and received from moving airborne and space borne vehicles. It does this without using heavy gimbals or moving prisms and mirrors commonly used by others with techniques that are much less accurate for laser beam angular tracking and pointing. Using lasers also can replace certain standard radio frequency transceivers used on orbiting satellites,” said Chuck Chalfant, president and CEO. “The patent title can put you to sleep but is descriptive.”

Space Photonics is a developer of space-qualified fiber optics, optoelectronics, anti-tamper technologies and free space optics equipment for space applications and earth-based deployments.
