Mobile phones soon to become small, efficient and flexible enough to be printed on clothing with the investigation of a new version of spaser - a nanoscale laser or nanolaser - technology

A spaser emits a beam of light through the vibration of free electrons, rather than the space-consuming electromagnetic wave emission process of a traditional laser.
PhD student and lead researcher Chanaka Rupasinghe said the modelled spaser design using carbon would offer many advantages.
Chanaka said other spasers designed to date are made of gold or silver nanoparticles and semiconductor quantum dots while our device would be comprised of a graphene resonator and a carbon nanotube gain element.
He said the use of carbon means our spaser would be more robust and flexible, would operate at high temperatures, and be eco-friendly.
Chanaka said because of these properties, there is the possibility that in the future an extremely thin mobile phone could be printed on clothing."
