Thinnest Nanolaser Developed Key To Future Optical Technologies

laser

Researchers have created the tiniest laser since its invention nearly 50 years ago

Developed by a consortium of researchers, dubbed the “spaser”, it is the thinnest laser ever developed. About 44 nanometers in diameter and about 10 times smaller than the wavelength of light, the nanolaser could pave way for superfast computers, which use light to process data instead of electrons currently used. This novel invention that emits visible light, has been brought about by harnessing clouds of electrons called “surface Plasmons,“ which produce photons of light waves.
