IBM Develops Electric Control of Light from Carbon Nanotubes

By fabricating an optical cavity around light-emitting nanotube mirrors at the bottom and top, wavelengths were confined to the desired 1.55-micron communications frequency. IBM researchers see a development path to light emitting nanotubes with no waste heat and a way to create a superlattice array of tubes for silicon photonic chips for optical computers. EETimes …
