We have been able to design the world's first 'spaser' - a nanoscale laser - made out of graphene and carbon. A spaser (surface plasmon amplication by stimulated emission of radiation) is effectively a nanoscale laser, or a nanonlaser. It has been touted as the future of optical computers and technologies. It could enable ‘nanophotonic’ circuitry, extremely small circuits far tinier than anything available today. This could usher in many technological advances including microchips hundred times more powerful than anything we have today.
'Our device would be comprised of a graphene resonator and a carbon nanotube gain element.'
'The use of carbon means our spaser would be more robust and flexible, would operate at high temperatures, and be eco-friendly'
