PhysOrg explains that circuits using lasers are already around, but tend to be too bulky to fit into your average TV set or smartphone. That might not be true for much longer, though:
Through this latest study, the researchers demonstrate how such lasers could be exploited to improve their performance and, potentially, lead to the miniaturisation of future technological devices. The research showcases how, in the future, new ‘bosonic lasers’ emitting terahertz radiation could be fine-tuned to vary or minimise the power required by the laser or to alter the intensity of terahertz radiation.
Dr Gabriela Slavcheva, from the [University of Bath] Department of Physics, said: “There are no such similar resources currently available and this research really opens up the way for new applications in medicine, biology, security, sensing and in high speed computers and high speed communications.
“The bosonic terahertz laser will work in tandem with a conventional light emitting diode (LED), which is a completely new approach. This will enable the miniaturisation of new optochips which, in turn, will help develop a whole new class of novel devices and applications.”
