Multifocal metalenses drive super-resolution imaging of brain organoids
Wei Ren, Qianxi Liang, Peng Xi
Published Published online: 24 October 2025 , doi: 10.37188/lam.2025.071
The generation of dense and uniform multifocal illumination patterns is essential for achieving rapid and artifact-free image scanning microscopy. Jo et al. introduced an innovative metalens design approach that facilitates the creation of low-pitch, uniform, and high-NA multifocal patterns, experimentally confirming its efficacy on biological samples.
Light-controlled biological microrobots precisely eliminate bio-threats
Bojian Shi, Yongyin Cao, Weiqiang Ding
Published Published online: 24 October 2025 , doi: 10.37188/lam.2025.069
Light-controlled biological microrobots employ near-infrared-activated macrophages to achieve precise navigation and targeted elimination of biological threats, such as micro/nanoplastics, yeast cells, S. aureus bacteria, and cellular debris, without the need for genetic modification. These biological microrobots enhance approaches to immunotherapy, infection control, and environmental remediation, all while overcoming conventional biocompatibility constraints.

A novel approach is presented for correcting chromatic aberration in full-color AR using an inverse-designed metasurface, enabling improved color accuracy and uniformity in diffractive waveguide combiners, with potential for more compact and efficient AR glasses.
Bridging microscale and macroscale light-field image reconstruction using ‘real-time and universal network’
Boya Jin, Yiwei Hou, Peng Xi
Published Published online: 20 August 2025 , doi: 10.37188/lam.2025.060
A real-time and universal network (RTU-Net) has been proposed for multiscale, real-time, high-resolution reconstruction of light-field images. The proposed RTU-Net can be applied to various application domains to gain insights into volumetric imaging from microscale to macroscale.
Towards fast spectroscopy using a practical all-fibre GHz dual-comb laser
Zihao Wang, Changxi Yang, Chengying Bao
Published Published online: 11 August 2025 , doi: 10.37188/lam.2025.051
A single-cavity all-fibre laser operating at GHz rates is demonstrated as a promising approach for fast spectroscopy. Multimode-interference-based spectral filtering in the laser enables dual-wavelength mode-locked pulse generation (thus, dual-comb emission) with a 148 kHz repetition rate difference. The GHz dual-comb laser exhibits excellent stability and can be used for outdoor measurements.
Solution-processed material innovation is sparking a research boom on X-ray imaging techniques

Published Published online: 04 August 2025 , doi: 10.37188/lam.2025.036
X-ray-responsive materials are often expensive and limited because of the monopolistic and complex high-temperature crystallisation technology required. Solution-processed material innovation offers a low-cost and vast design space for a new generation of X-ray detectors aimed at for high X-ray imaging performance.
Specialty optical-fibre sensors enable real-time contact measurement of multiple physiological parameters: towards all-fibre wearable devices
Daniele Tosi, Carlos Marques, Arnaldo Leal-Junior, Aliya Bekmurzayeva
Published Published online: 30 July 2025 , doi: 10.37188/lam.2025.054
The real-time measurements of surface physiological parameters, such as body temperature, cardiorespiratory rates, and sweat, is of increasing importance in healthcare. Optical fibres can offer an effective solution for contact sensing, as they enable multi-parameter and multi-point sensing while maintaining a compact form factor. Recent advances using chalcogenide and other specialty fibres represent a substantial step towards all-fibre wearable devices.
Surface lattice resonance promotes high-momentum, large-area 2D emission enhancement

Versatile on-chip polarization detection leveraging two-dimensional materials
Chao Ma, Shaofan Yuan
Published Published online: 30 June 2025 , doi: 10.37188/lam.2025.042
Hot carriers generated at the vicinity of the metal electrode in a WSe2 photodetector are extracted and amplified by a MoS2 field effect transistor, leading to a strong polarization-dependent photocurrent. This miniaturized polarization detection system assembled from two-dimensional materials enables new possibilities in optical communication and image recognition.
