A decade ago, the anti-laser made waves as a new type of perfect absorber that functions as a one-way trap door for light. Experiments have now demonstrated the control of light without absorbing it.

The authors use deep learning to detect and segment unlabeled and unaltered protein aggregates in living cells from transmitted-light images. The method provides a way to quantitatively study protein aggregation dynamics in a simple, fast and accurate way.

Coherent microwave-to-optical conversion is crucial for networking physically separated quantum devices. This paper demonstrates coherent conversion of microwaves to a wide, tuneable optical frequency range using room-temperature Rb atoms, supporting frequency division multiplexing and coherent frequency channel control.

Platicon microcombs in the normal-dispersion regime exhibit asymmetric spectral features because it largely relies on asymmetric local dispersion anomalies. The authors demonstrate stable, power-efficient microcombs with high spectral symmetry by means of symmetrical dispersion engineering.

Optical frequency combs enable precise measurement of optical frequencies, but integrated setups require a delicate balance between high precision and low power consumption. The authors demonstrate a sub-kHz-frequency measurement scheme based on a fully stabilized electro-optic comb that enables the parallel measurement of multiple wavelengths.

The condensed-matter counterpart of the Poincaré group may consist of various spacetime symmetry groups of spacetime crystals. In this work, the authors report the theoretical foundation of the projective spacetime symmetry algebras, explicitly work them out in (1,1) dimensions and discuss their consequences over spacetime lattices with gauge fluxes.

Molecular vibrations serve as valuable signatures for the constituent elements and bonding in compounds. Here, using Surface-Enhanced Infrared Absorption spectroscopy, the authors study refractive index dependent vibrations of surface phonon polaritons and surface plasmon platform, targeting dynamic biomonitoring.

We posit that inconsistent interpretations of experimental data have led to inaccurate claims on metalens focusing efficiencies. By performing a meta-analysis, we show that extraordinary claims of high focusing efficiency at high numerical apertures are, unfortunately, not yet backed by rigorous simulation or experimental results.

Precise measurements of the length of an Earth day are essential for understanding global mass transport phenomena. A ring laser gyroscope provides absolute measurements of variations in the length of the day with a resolution of 5 parts per billion over a 14-day period.

An outstanding scholar who pursues “interesting and useful, extreme and ultimate” in micro-nano manufacturing and optics.

Quasi-isothermal optofluidic streaming is enabled by symmetry-correlated laser scan sequences.
