Let’s think of the last time you sent data without wires. We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to transmit ...

You are watching a long-standing assumption in physics and engineering quietly fall apart. Researchers at Northwestern ...

The National Institute of Information and Communications Technology (NICT) has successfully demonstrated 2 Tbit/s Free-Space Optical (FSO) communication using small optical communication terminals ...

The surge in AI-driven high-speed computing and data transmission demands has prompted major players to invest heavily in ...

NASA is building optical communications technologies into its networks, using infrared laser links to offer missions higher data rates than comparable radio frequency systems. NASA’s Low-Cost Optical ...

Optical fibre communication systems have revolutionised global telecommunications by harnessing light‐based signal transmission through highly engineered glass or plastic fibres. The principle of ...

Free-space optical communications (FSOC), which use lasers for data transmission, are a promising approach for achieving high ...

Terahertz (THz) communication has emerged as one of the key technologies for sixth-generation (6G) wireless networks. Nevertheless, the transition to higher operational frequencies poses various ...

Inter-satellite communications via optical links are rapidly becoming the preferred means of transmission in space. This is opening up a dynamic new market for optical communications terminals and ...

To test the proposed architecture, the team characterized a commercialy available FB at the standard FSOC wavelength of 1550 nm. They measured different types of losses and distortion, simulated a ...
