Dynamic 3D metasurface holography via cascaded polymer dispersed liquid crystal

Microsystems & Nanoengineering
Metasurface with natural static structure limits the development of dynamic metasurface holographic display with rapid response and broadband. Currently, liquid crystal (LC) was integrated onto the metasurface to convert the passive metasuface into an ...

Size‐ and Depth‐Extended Aerial 3D Display Using Fresnel‐Lens‐Enhanced AIRR

Journal of the Society for Information Display, EarlyView.
A size‐ and depth‐extended three‐dimensional (3D) aerial display is realized by combining a light‐field display with a magnifying lens and a Fresnel‐lens‐enhanced aerial imaging by retro‐reflection (LeAIRR) system. The magnifying lens enlarges the virtual light‐field display plane without increasing the physical panel size, extending the aerial image ...

Wide‐Field Autostereoscopic 3D Display Enabled by Isolated Microlens Array and Gradual Radius Lens Design

Journal of the Society for Information Display, EarlyView.
This paper proposes an Isolated Microlens Array (I‐MLA) with Gradual Radius Lens (GRL) design for a wide‐field autostereoscopic floating 3D display in compact form. Extended coding pitch and directional mesh eliminate crosstalk, while radially varying microlens curvature maintains sharp images at large angles. Simulations show a practical continuous 40°

Augmented Reality Integration Improves Ergonomics in Dynamic Navigation for Dental Implant Surgery

Journal of the Society for Information Display, EarlyView.
This model‐based study demonstrates that integrating augmented reality (AR) to project X‐Guide navigation data directly onto the surgical field eliminates attention shifts between the patient and monitor, enhancing ergonomic efficiency. The AR system, which projects digital guidance directly into the surgeon’s line of sight, achieved high precision and

Thin Maxwellian Virtual Reality Near‐Eye Display Using Holographic Optical Element and Mini‐Fresnel Lens Array

Journal of the Society for Information Display, EarlyView.
A thin Maxwellian‐view VR near‐eye display based on a holographic optical element (HOE) is presented. Integrating the HOE with the display panel eliminates the structural gap, achieving an 8‐mm internal spacing. Accommodation‐independent image sharpness is experimentally verified over a 0‐ to 3.3‐D range, mitigating the vergence–accommodation conflict.

Recent Advances in Photonic Bound States in the Continuum: From Fundamentals to Engineering and Implementation

Laser &Photonics Reviews, EarlyView.
This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...

Optically Bound Rapid Plasmonic Nanorod Dimers: Anisotropic Dynamics Driven by Light‐Fluidic Cooperation

Laser &Photonics Reviews, EarlyView.
Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.
