The researcher believes that this advance may pave the way for “nanolasers” that can probe and manipulate DNA.
It may also prove helpful in creating super-fast computers and for telecommunications, the researcher says.
“This work shatters traditional notions of laser limits and makes a major advance towards applications in the biomedical, communications and computing fields,” the Scotsman quoted
According to Prof.
Plasmons are the wave-like motions of excited electrons on the surfaces of metals. Binding light to these oscillations allows it to be squeezed much further than normal.
“Plasmon lasers represent an exciting class of coherent light sources capable of extremely small confinement. This work can bridge the worlds of electronics and optics at truly molecular length scales,” said
The research team behind this breakthrough hope that one day they will be able to shrink light down to the size of an electron’s wavelength, about one billionth of a metre.
A research article on their latest work has been published in the journal Nature.
