Professor Drake's research centers on nonlinear optics in microscopic photonic structures.

Our current focus is on "microcombs" -- optical frequency combs formed in dielectric microring resonators via cascaded four-wave mixing. Microcombs are key components in compact optical atomic clocks and optical synthesizers, on-chip spectrometers, and integrated quantum systems.

Besides developing microcombs for novel applications, we also study the rich array of nonlinear processes within our microresonators which lead to exotic phenomena such as self-organizing soliton crystals and laser cooling of light.
