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 ...

Free-space QSDC does not require the laying of optical fibers, which can effectively prolong the transmission distance and break the limitation of terrain. It is one of the solutions to the "last mile ...

South Korean researchers have successfully developed technology to mass-produce quantum dot lasers, widely used in data centers and quantum communications. This breakthrough paves the way for reducing ...

Using two RSOAs to completely erase the downstream data and then using MZM to modulate four optical carriers is worthwhile as they avoid the requirement for multiple lasers with selected wavelengths ...

The Internet of Underwater Things (IoUT) is revolutionizing underwater communication by enabling real-time data exchange, environmental monitoring, and exploration in aquatic environments. Among ...
