Nano-opto-mechanical metamaterials on semiconductor nanomembranes are a perfect platform for parametric optical devices, frequency mixing and optical comb generation, and fundamental studies of coupling between thermal excitations in metamaterials an

We demonstrate optical metrology for two-dimensional sub-wavelength objects with resolution beyond λ/50 via deep learning-enabled analysis of light scattering from target objects illuminated by the phase singularity of superoscillatory structured li

We show how the exploitation of phase singularities in topologically structured light fields can enable dramatic sensitivity improvements in diffraction-based optical displacement and dimensional metrology.

The first realization of optical pico-motion metrology is reported. The position of a nanowire is localized with ‘sub-Brownian’ precision better than 100 picometers via deep learning analysis of topologically structured light scattering from the

A continuous time crystal state can be realised in a nano-opto-mechanical metamaterial - light resonant with the metamolecules’ plasmonic mode triggers a spontaneous transition to a state characterised by transmissivity oscillations resulting from

We introduce a new ‘optical ruler’ concept, which allows for single-shot, real-time detection of nanometric displacements down to λ/400, through the visualization of singularities in a topologically structured optical field using a polarization-
