Natural Crystal Structure for Generating Raman‐Like Orbital Angular Momentum States

Advanced Science, EarlyView.
This work proposes a strategy for symmetry breaking of the degenerate OAM states relying on the natural anisotropy of crystal gain, to select the handedness of the spatial spiral phase front and further tunable Raman‐like OAM states by thermal‐driven, which clarifies the contribution of intrinsic crystal property to the OAM states and opens a new route

Large Built‐in Fields and Tunable Ferroelectricity in Composition‐Graded ScAlN Thin Films Deposited by Reactive Sputtering

Advanced Science, EarlyView.
This study explores composition‐graded ScxAl1‐xN thin films grown by large‐scale and CMOS‐compatible sputtering that can effectively suppress abnormally‐oriented grains. Importantly, their ferroelectric properties can also be tuned owing to large built‐in fields induced by chemical/polarization gradient.

Single‐Pixel Infrared Miniaturized Spectrometer Enabled by Ultra‐Broadband Reconfigurable Photodetection

Advanced Science, EarlyView.
A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,
