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 ...
Coherent optical communication systems harness the properties of laser light to transmit high-speed data over long distances with exceptional spectral efficiency. These systems detect both the ...
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 ...
Figure 1: NICT's 7.4 km, 2 Tbit/s horizontal propagation experiment (April 2025). The ST terminal was used as the transmitter and the FX terminal as the receiver. The terminals exchanged pseudo-random ...
A silicon-lithium niobate metasurface controls light through air at gigahertz speeds, advancing compact systems for optical communication and signal routing. (Nanowerk Spotlight) Optical systems that ...
An explosion of data, driven by more sensors everywhere and the inclusion of AI/ML in just about everything, is ratcheting up the pressure on data centers to leverage optical interconnects to speed up ...
