Nanopillar Confining Light (image) University of California - Berkeley Caption The unique structure of the nanopillars grown by UC Berkeley researchers strongly confines light in a tiny volume to enable subwavelength nanolasers. Images on the left and top right show simulated electric field intensities that describe how light circulates helically inside the nanopillars. On the bottom right is an experimental camera image of laser light from a single nanolaser. Credit Connie Chang-Hasnain Group Usage Restrictions Must include credit with use.
