> German researchers have combined photonics and electronics to create a world-record-breaking wireless network that can send and receive data at a heady 100 gigabits per second (Gbps). This beats the same team’s previous world record of 40Gbps...
> To achieve such a massive data rate, researchers from the Karlsruhe Institute of Technology (KIT) used a massive swath of bandwidth at around 240 GHz close to the terahertz frequency range. To create the signal, two laser beams (carrying the data) are mixed together (using a photon mixer made by NTT Electronics). An electrical signal results, where the frequency of the signal (237.5 GHz in this case) is the difference between the two optical signals. A normal antenna is then used to beam the signal to the receiver, where a fancy chip...
