IBM claims photonics speed record

Abstract:
"The previous delay lines based on ring resonators occupied a few square centimeters on a chip, making our delay line with micron-sized rings orders of magnitude (more than 100 times) smaller," said Yurii Vlasov, who is also a member of the research staff. "But it is not the small size of our device, even, that is most impressive," he said. "Rather it is the level of control we achieved in our waveguide dimensions —the gap between the waveguide and the ring, for instance, has to be precisely controlled to within just a few nanometers, making our device the world's first to qualify as silicon optical nanotechnology."
