Free-Space Optical Communications Soar with the Satellite Sector

Facebook X LinkedIn Email
Optical free-space networks have a secure future in ground-to-space and space applications. But companies in the market for the long run see considerable untapped potential in the terrestrial market as well.

MARIE FREEBODY, CONTRIBUTING EDITOR

Free-space optics (FSO) and systems are uniquely valuable in enabling fast and secure connectivity, both in terrestrial and nonterrestrial networks. With major advancements in space optics over the last 20 years, ultrahigh-bandwidth signals now regularly ping back and forth over great distances, providing a communications canopy that extends over the entire globe. A typical free-space communications concept applied in a low-Earth-orbit satellite constellation. Each satellite carries four optical communications terminals that link to neighboring satellites in each direction to form a...Read full article

    integrated photonics
    Integrated photonics is a field of study and technology that involves the integration of optical components, such as lasers, modulators, detectors, and waveguides, on a single chip or substrate. The goal of integrated photonics is to miniaturize and consolidate optical elements in a manner similar to the integration of electronic components on a microchip in traditional integrated circuits. Key aspects of integrated photonics include: Miniaturization: Integrated photonics aims to...
