Scalable Lithium Niobate Nanoimprinting for Nonlinear Metalenses

open access: yesAdvanced Materials, Volume 37, Issue 27, July 10, 2025.
A broadband polycrystalline lithium niobate platform is developed for highly versatile and scalable fabrication of nonlinear metasurfaces. This work demonstrates simultaneous second harmonic generation and wavefront‐shaping via a metalens on this platform.

Extraction of Inherent Amplitude Mode from a Light Beam

open access: yesAdvanced Photonics Research, Volume 6, Issue 7, July 2025.
Mode extraction is the inverse process of the double‐beam superposition principle in classical optics. While polarization mode extraction has been successfully demonstrated using an m‐order vector vortex beam, this article demonstrates the amplitude mode extraction of a light beam.

Reconstructing Three‐Dimensional Optical Anisotropy with Tomographic Müller‐Polarimetric Microscopy

open access: yesAdvanced Science, Volume 12, Issue 27, July 17, 2025.
Tomographic Müller polarimetric microscopy is a novel imaging technique that resolves 3D birefringent properties of bulky samples, unveiling hierarchical nanostructures at microscopic resolution. Based on incoherent visible‐light polarimetry, it achieves experimental simplicity by eliminating phase measurements.

METHOD FOR PLANE NEAR-FIELD ACOUSTIC HOLOGRAPHY BASED ON COMPRESSIVE SAMPLING AND ITS APPLICATION

open access: yesJixie qiangdu, 2016
In traditional plane near-field acoustic holography reconstruction process,regardless of wave number domain filter or regularization method,they cannot solve their own ill-posed problem,and thus cannot improve the reconstruction accuracy.

Speckle decorrelation in Ultrasound-modulated optical tomography made by heterodyne holography

open access: yes, 2016
Ultrasound-modulated optical tomography (UOT) is a technique that images optical contrast deep inside scattering media. Heterodyne holography is a promising tool able to detect the UOT tagged photons with high efficiency.
