Selective Color Appearance of Liquid‐Crystal‐Aided Laser‐Induced Periodic Surface Structures

Advanced Optical Materials, EarlyView.
Self‐assembled nano trenches on transparent electrodes are produced by irradiating femtosecond laser, and then combined with liquid crystal, showing brilliant selective color, which is electronically switchable. The nano trenches diffract light, and those totally internally reflected light propagates in the liquid crystal cell.

Plasmonic and Photonic Modes in Colloidal CuS Nanocrystals

Advanced Optical Materials, EarlyView.
Copper sulfide in the covellite phase (CuS) can exhibit exceptional optoelectronic properties with plasmonic and photonic absorption in its monolithic nanomaterial form. In this work, the phenomenon of near‐infrared (NIR) to visible electromagnetic field localization in ultrathin crystalline quasi‐2D CuS nanocrystals is demonstrated by mapping ...

3D Printed Optics Achieves Broadband Structured Light

Advanced Optical Materials, EarlyView.
The arbitrary creation of structured light often requires complex design and fabrication steps and is largely limited to single wavelength. By leveraging off the toolkit for digital holograms, how complex amplitude modulation can be implemented as 3D printed optics in a manner that is broadband is shown, for the creation of multiwavelength forms ...

Simultaneous Perfect Anomalous Reflection and Angle of Arrival Sensing in Reconfigurable Intelligent Surfaces

Advanced Optical Materials, EarlyView.
A reconfigurable intelligent surface is proposed that can simultaneously anomalously reflect the light and sense the angle of arrival. An in situ optimization of either the currents flowing on array elements or the far field in the receiver direction realizes anomalous reflection and suppresses parasitic scattering.

Helical Ladder Oligomers Exhibit Amplified Circularly Polarized Emission

Advanced Optical Materials, EarlyView.
The discovery that a multi‐helicene system based on a series of annulated [6]helicenes and perylenediimides, exhibits larger‐than‐linear amplification of glum with helicene length is described. It is also observed large enhanced fluorescent quantum yields and large extinction coefficients for this length series.
