| Unique properties of graphene lead to a new paradigm for low-power telecommunications Posted: 15 Jul 2012 11:14 AM PDT Engineers have demonstrated remarkable optical nonlinear behavior of graphene that may lead to broad applications in optical interconnects and low-power photonic integrated circuits. The researchers used graphene to transform the originally passive device into an active one that generated microwave photonic signals and performed parametric wavelength conversion at telecommunication wavelengths. Showing the power-efficiency of the device, they say, is an important advance in building all-optical processing elements essential to faster, more efficient, modern telecommunications.  |
