All Year All Twisted microdomains in liquid crystals for polarization-insensitive phase modulation Yifei MaZimo ZhaoChao He News & ViewsOpen Access05 Jan 2024 Ultrahigh-fidelity spatial mode quantum gates in high-dimensional space by diffractive deep neural networks We showcase the use of deep diffractive neural networks to construct a series of high fidelity and high-dimensional quantum gates, which are encoded by the spatial modes of photons. Qianke WangJun LiuJian Wang ArticleOpen Access05 Jan 2024 Ultra-simplified diffraction-based computational spectrometer Ultra-simplified compact spectrometer with a simple, arbitrarily shaped pinhole as the diffracted disperser, eliminating need for encoding and full spectrum calibration, and achieving better than 3 nm spectral peak resolution. Chuangchuang ChenHonggang GuShiyuan Liu ArticleOpen Access05 Jan 2024 Cavity-enhanced photoacoustic dual-comb spectroscopy We demonstrate cavity-enhanced photoacoustic dual-comb spectroscopy with a flute-type acoustic resonator and an optical cavity for spectral measurements with ultra-high sensitivity, high resolution, and broad bandwidth.

Kaiqiang WangLi SongEdmund Y. Lam Review ArticleOpen Access01 Jan 2024 Label-free biosensing with singular-phase-enhanced lateral position shift based on atomically thin plasmonic nanomaterials We developed a novel label-free plasmonic biosensing configuration for sub-femtomolar (10−16 M) small molecule detection with an ultra-high sensitivity of 1.72 × 108 nm RIU−1 and a large figure of merit (FOM). Shaodi ZhuRodolphe JaffiolShuwen Zeng ArticleOpen Access01 Jan 2024 Dynamics of self-hybridized exciton–polaritons in 2D halide perovskites Self-hybridized exciton–polaritons are shown to enable sub-bandgap absorption and emission in 2D perovskites. The energy absorbed by the perovskites are also found to transfer to few-layer graphene in a heterostructure. Surendra B.
