Unique Properties of Graphene Lead to a New Paradigm for Low-power Telecommunications


July 15, 2012

graphene on silicon photonic crystal nanomembranes Columbia University 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.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
