On-chip quantum optical frequency comb sources
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. ©

High‐Efficiency InGaP‐on‐Insulator Microresonator Nonlinear Conversion and Entanglement Generation
Sulfur treatment of InGaP‐on‐Insulator (InGaP‐OI) significantly reduces surface roughness, passivates surface states, and lowers propagation loss at visible wavelengths, enabling efficient nonlinear frequency conversion and photon‐pair generation.

A scalable laser‐assisted surface patterning method regulates zinc ion flux and promotes lateral epitaxial growth for stable aqueous batteries. Periodic micro‐holes effectively minimize interfacial resistance and reconstruct the zinc texture to favor the compact (002) basal plane. This structured anode suppresses both dendrite propagation and parasitic

Advancing Energy Materials by In Situ Atomic Scale Methods
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

In Situ Contact Angle Measurement for Autonomous Spin Coating in Self‐Driving Labs
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.

Ultrafast RF Spectrum Analyzer Assisted by Optical Short‐Time Fourier Transform
We present Recent efforts in an ultrafast RF spectrum analyzer based on the short‐time Fourier transform (STFT) at over 10 MHz frame rate and over 40GHz bandwidth to improve performance and support applications. All these efforts could inspire more innovative applications of temporal imaging modalities in the future.

Experimental analysis of four-wave mixing in a semiconductor optical amplifier using frequency resolved optical gating [PDF]
Four-wave mixing was performed in a multi-quantum well semiconductor optical amplifier in order to demultiplex 2 ps pulses from 80 GHz to 10 GHz. The demultiplexed pulses were measured using frequency resolved optical gating.

Hybrid Kerr-electro-optic frequency combs on thin-film lithium niobate
Optical frequency combs are indispensable links between the optical and microwave domains. Chip-scale integration promises compact, scalable, and power-efficient frequency comb sources, enabled by the resonantly-enhanced Kerr effect or the electro-optic ...
