On-chip quantum optical frequency comb sources
, 2018 Integrated optical frequency comb sources, based on nonlinear microring resonators, can be used to generate complex quantum states. In particular, we achieved multi-photon and high-dimensional entangled quantum states, as well as their coherent control. ©

Advanced Science, EarlyView.Negative‐gauge‐factor materials reverse the usual rule of piezoresistive sensing: their resistance falls, rather than rises, under deformation. This review organizes such behavior into four mechanistic classes spanning intrinsic semiconductors, composites, conducting polymers, and engineered architectures.

Mechanical Control of a Microrod-Resonator Optical Frequency Comb
Physical Review X, 2013 We report on the stabilization of a microresonator-based optical frequency comb (microcomb) by way of mechanical actuation. These experiments use novel CO_{2}-laser-machined microrod resonators, which are introduced here and feature optical Q≳5×10^{8 ...

In Situ Contact Angle Measurement for Autonomous Spin Coating in Self‐Driving Labs
Advanced Intelligent Discovery, EarlyView.A vision‐based add‐on transforms commercial spin coaters into autonomous modules of Self‐Driving Labs. Combining a width‐scaled U‐Net with classical geometric analysis, the system simultaneously measures contact angles and estimates substrate pose using a single camera.
