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 ...

Laser &Photonics Reviews, EarlyView.An optical approach is proposed for real‐time and high‐precision detection of the magnetostrictive deformation of an yttrium‐iron‐garnet sphere in three dimensions, based on the deformation induced spatial high‐order modes of the scattered field, postselection, and balanced homodyne detection.

Laser &Photonics Reviews, EarlyView.This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.

Integrating human acceptance into habitat suitability models for snow leopards in northern Bhutan
People and Nature, EarlyView.Abstract Habitat suitability models are commonly used to assess the potential distribution of large carnivores by identifying ecologically favourable areas. However, these models often overlook human dimensions, such as conflict and acceptance, which can lead to overestimation of species ranges and a mismatch between predicted and actual distributions.

Digital surveillance of animals and nature recovery
People and Nature, EarlyView.Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.
