Tunable Patterned Blue Phase Liquid Crystals Based on Lithographic Process Technology

Advanced Optical Materials, EarlyView.
A patterned blue phase liquid crystal device with electrically driven, localized bistability is demonstrated using a cost‐efficient photolithographic dual‐alignment process. The device switches between a high‐contrast patterned state and a uniform reflective state.

An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...

Toward Rapid Low‐Cost Fabrication of Single‐Nanowire Photodetectors via the Utilization of Dielectrophoresis

Advanced Photonics Research, EarlyView.
A scalable, low‐cost approach for assembling single germanium nanowires (NWs) into photodetectors is demonstrated using a modified dielectrophoresis method with a voltage‐divider circuit. This self‐limiting assembly technique achieves ultrahigh responsivity (>6 × 105 A W−1) at 700 and 1550 nm without requiring nanoscale electrodes, offering a versatile
