(a) Optical microscope image of the racetrack resonator. (b) SEM image of the cross-section of the silicon structure. The different thickness in the coupling region is a result of the slower oxidation rate in the gap region.
Michal Lipson does groundbreaking research on nanophotonics—“optics on a very, very small scale." In this interview for Fusion’s “Genius” series she explains how nanophotonics could revolutionize the way computers work.
