A team of researchers affiliated with a host of institutions in China has developed an ultrafast optoelectronic switch using a Bose-Einstein condensate of polaritons. They published their work in the journal Physical Review Letters.
As scientists look for ways to create faster devices, they have turned to light as an information transfer medium instead of electrons. In order to create such devices, switches must be developed that can handle the faster medium that operates at optical frequencies. In this new effort, the researchers have designed and built just such a switch—one that allows for processing in the terahertz range.
