Introduction

Wavefront shaping is a powerful tool in modern photonics, enabling precise control over how light propagates through free space and complex media. Conventionally this control comes from a single phase plane displayed on a spatial light modulator (SLM), yet one plane cannot realise the many-to-many mappings that tasks such as mode sorting, optical routing, and arbitrary basis...

Surface-emitting semiconductor lasers provide a highly adaptable, compact and integrable light source for a range of rapidly growing applications, spanning consumer devices, data-centre interconnects, 3D sensing, and the automotive and robotics industries. Vertical-cavity surface-emitting lasers (VCSELs) are the most mature devices in this category, achieving surface emission through...

Metasurfaces offer unprecedented control over light-matter interactions at the nanoscale and have emerged as a promising platform for nonlinear and quantum photonic applications [1]. Particularly, metasurfaces optimised for spontaneous parametric down-conversion (SPDC) serve as compact and highly customisable sources of entangled photon pairs [2]. However, it remains challenging to identify...

754. Tailoring High-Refractive-Index ZrO₂ Nanocomposites for Scalable Manufacturing of Ultraviolet Metasurfaces

Ultraviolet metasurfaces offer powerful opportunities for compact optical systems, including holography, imaging, display, and biosensing. However, their practical implementation remains challenging because UV metasurfaces require deeply subwavelength, high-aspect-ratio nanostructures as well as materials with high refractive indices and low optical loss in the ultraviolet region. Nanoimprint...

Optical skyrmions are topological structures that have attracted significant interest due to their robustness and versatility across a wide range of optical platforms. In quantum optics, they have emerged as a promising resource for robust quantum information encoding. However, existing methods for generating optical skyrmions typically rely on bulky optical systems and are generally limited...
