Metasurfaces, two-dimensional planar optical devices based on subwavelength-scale structures, have garnered significant attention for their potential to replace conventional optical components in various fields. These de...

Memristors are considered key building blocks for developing neuromorphic or in-memory computing hardware. Here, we study the ferroelectric and memristive response of Pt/Ca:HfO2/Pt devices fabricated on silicon by spinco...

Exciton–polariton condensation in optical resonators is a fascinating pathway to realise ultra-coherent states of light, underpinned by Bose–Einstein quasiparticles. Bearing inherently non-radiative nature, bound sta...

Finite-size effects occurring for quasi-bound states in the continuum (qBICs) formed in symmetric and asymmetric all-dielectric waveguide grating couplers are investigated using numerical simulations for different config...

Nanogap cavity metasurfaces – an array of metallic nanoparticles separated from a metal plane by a nanometer-scale dielectric material – can manipulate electromagnetic waves across a wide wavelength range. Through th...

The combination of advanced photoelectric detectors has rendered single-band camouflage materials ineffective, necessitating the development of infrared multispectral camouflage. However, the design and fabrication of ex...
