Control over the dispersion of the refractive index is essential to the performance of most
modern optical systems. These range from laboratory microscopes to optical fibres and even …

Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

Metasurfaces can be programmed for a spatial transformation of the wavefront, thus allowing
parallel optical signal processing on-chip within an ultracompact dimension. On-chip …

Periodic structures with a sub‐wavelength pitch have been known since Hertz conducted his
first experiments on the polarization of electromagnetic waves. While the use of these …

Nanoscale surface texturing, drilling, cutting, and spatial sculpturing, which are essential for
applications, including thin-film solar cells, photonic chips, antireflection, wettability, and …

The study of the resonant behavior of silicon nanostructures provides a new route for
achieving efficient control of both electric and magnetic components of light. We …

The realization of gigahertz bandwidth modulators out of silicon-based technology in the
early 2000s marked a cornerstone of silicon photonics development. While modulation …
