Monochromatic light can be characterized by its three fundamental properties: amplitude,
phase, and polarization. In this work, we propose a versatile, transmission-mode all …

The term Poincaré beam, which describes the space-variant polarization of a light beam
carrying spin angular momentum (SAM) and orbital angular momentum (OAM), plays an …

The pace of innovations in the field of optical trap** has ramped up in the past couple of
years. The implementation of structured light, leading to groundbreaking inventions such as …

As the two most representative operation modes in an optical imaging system, bright-field
imaging and phase contrast imaging can extract different morphological information on an …

Vortices arise in many natural phenomena as dark points of total destructive interference.
Sometimes they form continuous lines and even enclosed loops with knotted or linked …

As the 2D counterpart of metamaterials, metasurfaces have drawn wide attentions in recent
years due to their unique electromagnetic (EM) properties and subwavelength footprints …
