The cool thing here is that the researchers at Australia’s Monash University have created a very tiny laser that uses surface plasmons and is made of carbon. That’s pretty neat by itself!
The press release linked below, however, goes a bit farther:
The carbon means that it could, possibly, be made by printing it on flexible substrates, which could, possibly, include clothes. The device might, possibly, be able to replace some or many of the components in a cellphone. Therefore, the press release title claims: Your T-shirt’s ringing: telecommunications in the spaser age.
