Customizing 3D Polarization Structures at Second Harmonic Frequency

Laser &Photonics Reviews, EarlyView.
The nonlinear optical metasurfaces that can generate second harmonic waves (SHWs) and manipulate 3D polarization structures are designed and fabricated. Based on the concept of nonlinear geometric phase, the desired phase distributions of the SHWs are encoded onto the metasurfaces by using gold C3 meta‐atoms.

Are physiological oscillations physiological?

The Journal of Physiology, EarlyView., 2023
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Orbital Angular Momentum Meta‐Holography with Full‐Polarization Control

Laser &Photonics Reviews, EarlyView.
This work demonstrates full‐polarization‐controlled orbital angular momentum (OAM) holography using a single‐layer dielectric metasurface. By independently modulating the complex‐amplitude distributions of two circular polarizations, arbitrary spatially varying polarization is achieved while preserving OAM properties.

High‐Resolution 3D Imaging with Tunable Point Cloud Projection Based on Meta‐Device

Laser &Photonics Reviews, EarlyView.
A meta‐based tunable point cloud projection that enables high‐resolution 3D imaging through a dynamic meta‐device is demonstrated. By adjusting spatial sampling, the system achieves significantly sharper reconstructions while remaining compact. The innovation opens new possibilities for applications such as facial recognition, augmented reality, and ...

A Linear‐to‐Linear Cross‐Polarization Conversion q‐BIC Metasurface for Transmission Mode Mid‐Infrared Spectral Filtering

Laser &Photonics Reviews, EarlyView.
Manipulating the ultranarrow linewidth spectral features of quasi bound states in the continuum is challenging. A metasurface supporting linear‐to‐linear cross‐polarization coupling efficiency surpassing 25% is proposed to address the issue. Less than 100 nm linewidth is achieved, enabling the device to be applied to wavelength‐selective polarization ...
