Rice University researchers have discovered a fundamentally different form of light-matter interaction in their experiments with gold nanoparticles.
They weren’t looking for it, but students in the lab of Rice chemist Stephan Link found that exciting the microscopic particles just right produced a near-perfect modulation of the light they scatter. The discovery may become useful in the development of next-generation, ultrasmall optical components for computers and antennas.
