Cylindrical vector beams and vortex beams, two types of typical singular optical beams
characterized by axially symmetric polarization and helical phase front, possess the unique …

Optical frequency combs, a revolutionary light source characterized by discrete and equally
spaced frequencies, are usually regarded as a cornerstone for advanced frequency …

A survey of some recent theoretical and experimental studies on localized structures that
form and propagate in a broad class of optical and matter-wave media is presented. The …

The cylindrical rogue wave (RW) and breathers in a collisionless, unmagnetized, and warm

Manganese dioxide (MnO2) is a widely used and well-studied 3-dimensional (3D) transition
metal oxide, which has advantages in ultrafast optics due to large specific surface area …

We theoretically investigate the possibility of a passive mode-locking regime in a two-section
laser with an ultrashort cavity of the length around ten wavelengths of the medium resonant …

This work has demonstrated the potential of a reduced graphene oxide silver/polyvinyl
