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°

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 ...

Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Octave‐Spanning, Deterministic Single Soliton Generation in 4H‐Silicon Carbide‐On‐Insulator Microring Resonators

Laser &Photonics Reviews, EarlyView.
The miniaturization of metrology and precision spectroscopy systems requires robust, turn‐key microcombs with broad bandwidth, low threshold, and high efficiency. Here, high‐Q, dispersion‐engineered microresonators in a high‐confinement nonlinear SiC platform, combined with waveguide‐enabled thermal management and laser cooling, enable deterministic ...

Non‐Uniform Programmable Photonic Waveguide Meshes

Laser &Photonics Reviews, EarlyView.
Integrating defect cells into uniform hexagonal waveguide meshes overcomes the fundamental spectral and temporal limitations of programmable photonics. By leveraging the Vernier effect through non‐uniform coupled cavities, this architecture achieves a tenfold increase in free spectral range and ultra‐fast sampling times, paving the way for next ...
