With micro-resonators (fabricated in house or by collaborators) we are developing microcombs, integrated reference cavities and low-noise laser sources. The
nanophotonic

Nonlinear nanophotonic control of light

Ongoing
Nonlinear optics enables transformation of optical fields through light-matter interactions. These transformations strictly conserve energy and phase-matching
yb optical clock

Yb Optical Lattice Clock

Ongoing
The very best atomic clocks today are known as optical clocks, because their timebase resides at a very high frequency (~10 15 Hz), corresponding to the optical
