Single-Shot Wavefront Sensing in Focal Plane Imaging Using Transformer Networks
OpticsWavefront sensing is an essential technique in optical imaging, adaptive optics, and atmospheric turbulence correction. Traditional wavefront reconstruction methods, including the Gerchberg–Saxton (GS) algorithm and phase diversity (PD) techniques, are ...

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 ...

Phase‐Retrieved High‐Throughput Multi‐Channel Simultaneous Surface Plasmon Resonance Detection
Laser &Photonics Reviews, EarlyView.This work presents a new phase‐retrieval high‐throughput multi‐channel simultaneous SPR detection framework. By integrating an objective lens‐based coupling system with a rotation‐based ePIE (r‐ePIE) phase retrieval on the back focal planes, this framework significantly reduces the minimum required detection area to reveal localized information.

Pupil Plane Multiplexing for Vectorial Fourier Ptychography
Laser &Photonics Reviews, EarlyView.This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.

Journal of Astronomical Telescopes Instruments and Systems, 2018 . The generation of Extremely Large Telescopes (ELTs) with mirror diameters up to 40 m has thick secondary mirror support structures (also known as spider legs), which cause difficulties in the wavefront reconstruction process.

Mode‐Locked Pulse Generation in Plasmonic Lattices
Laser &Photonics Reviews, EarlyView.The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

MetalMat, EarlyView.This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.
