Terahertz waves, operating at a much higher frequency than microwaves, could one day be used to carry data many times faster than today’s cellular and Wi-Fi networks. More work needs to be done before terahertz technology is deployed, but a Brown-led research team has made progress on one important part: multiplexing and de-multiplexing a terahertz stream.
Terahertz radiation could one day provide the backbone for wireless systems that can deliver data up to one hundred times faster than today’s cellular or Wi-Fi networks.
