Carbon‐Coated Moth‐Eye Structure: An Ultrabroadband THz‐DUV Near‐Perfect Absorber

Advanced Optical Materials, EarlyView.
A silicon moth‐eye surface coated with pyrolytic carbon achieves >98% absorption from 1 to 1200 THz by combining gradient‐index matching with PyC's broadband conductivity, forming an ultra‐broadband absorber from THz to deep UV. Experimental results and simulations agreed well.

C2LI: Enhancing Structural Color Sensing and Imaging via Complementary Color Laser Illumination

Advanced Optical Materials, EarlyView.
This article introduces complementary color laser illumination (C2LI) and demonstrates it to be an effective approach for engaging the visual system to enhance perceptual sensitivity and chromatic contrast. This enhances a human user's ability to detect subtle differences in sample or medium characteristics, enabling novel applications in colorimetric ...

Size Effect on Photothermal Heating Ability of Gold Bipyramids

Advanced Optical Materials, EarlyView.
Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

Mechanically Tunable Optical Response in Silicon Nanosphere Metasurface Fabricated via Bottom‐Up Process

Advanced Optical Materials, EarlyView.
A large area mechano‐tunable square lattice array of silicon nanospheres is fabricated by a bottom‐up process, and the capability to tune the lattice resonances by external strain is demonstrated. Spectrally overlapping the electric and magnetic dipole lattice resonances by mechanical strain induces the lattice Kerker effect and strongly suppresses the
