Polarization‐Controlled Transmissive Plasmonic Color Filter Using a Dimer‐Aperture Array

Advanced Science, EarlyView.
An aluminum dimer aperture array plasmonic metasurface is proposed and fabricated to achieve efficient polarization‐color filtering with CMOS‐compatible materials. The structure's simultaneous polarization‐color filtering capability is shown using structural color generation, where color gamut coverage of 76% and extinction ratio over 20 is achieved ...

Accuracy characterization of Shack–Hartmann sensor with residual error removal in spherical wavefront calibration

Light: Advanced Manufacturing
The widely used Shack–Hartmann wavefront sensor (SHWFS) is a wavefront measurement system. Its measurement accuracy is limited by the reference wavefront used for calibration and also by various residual errors of the sensor itself.

Achromatic 3D Multi‐Color Orbital Angular Momentum Holography

Advanced Science, EarlyView.
This work presents an achromatic 3D multicolor orbital angular momentum (OAM) holography based on spatial multiplexing. By integrating wavelength‐specific lens functions onto monochromatic Fourier OAM‐dependent holograms and high‐resolution spatial discretization and interleaving via two‐photon lithography (TPL), the approach addresses axial chromatic ...
