Stereopsis–Occlusion Conflicts Impair Visual Performance in Augmented Reality

Journal of the Society for Information Display, EarlyView.
Stereopsis‐occlusion conflicts occur when AR augmentations are rendered behind real‐world physical objects without handling occlusion. This study shows that these conflicts can be more detrimental to visual performance than vergence‐accommodation conflicts, especially for augmentations of far objects.

Discrete Chiral Ballistic Polariton Laser

Laser &Photonics Reviews, EarlyView.
Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.

Space‐Time‐Modulated Metasurface Enabled High‐Performance Near‐Field Focusing with Enhanced Phase Modulation

Laser &Photonics Reviews, EarlyView.
This study leverages STM technology to enhance NFF performance by enabling continuous phase control at the +1st harmonic without increasing hardware complexity. It overcomes the limitations of conventional 1‐bit TMs caused by phase quantization errors and demonstrates that even compact arrays can achieve effective focusing, highlighting the strong ...

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.

A Dual‐Programmable Metasurface with Duplex Beam Steering for Full‐Space Terahertz Communications

Laser &Photonics Reviews, EarlyView.
A dual‐programmable terahertz metasurface enables independent control of transmission and reflection beam steering. It breaks through the limitations in resonant tunability by polarization allocation with 2D‐electron‐gas tuning, enabling a single resonator to incorporate bidirectional operating modes.

Topological Vortex Transition Induced by Spin Hall Effect of Light for Tunable Humidity Sensing and Imaging

Laser &Photonics Reviews, EarlyView.
This study introduces a humidity‐responsive optical imaging technique capable of dynamically switching between edge detection and bright‐field imaging modes. Utilizing humidity‐induced modulation of refractive index and polarization‐dependent beam shaping, tunable optical imaging is achieved through controlled beam splitting governed by the spin Hall ...
