Alemán lab: Discovery leads to ultrasensitive way to measure light
A team of UO physicists has drummed up a new way of measuring light: using microscopic drums to hear light.
The technology out of the Alemán Lab, known as a “graphene nanomechanical bolometer,” leverages a promising new method and material to detect nearly every color of light at high speeds and high temperatures.
“This tool is the fastest and most sensitive in its class,” said Benjamín Alemán, a professor of physics and a member of the UO’s Center for Optical, Molecular, and Quantum Science and an associate of the Phil and Penny Knight Campus for Accelerating Scientific Impact.
The device offers an alternative to the conventional way of using electricity to measure light, as found in devices like a smartphone’s camera. Instead, this mechanical method captures the vibrations of infinitesimally thin drums that are caused by light. The physicists obtain measurements by listening to the sound of the light absorbed by the drumhead.
