Noise is usually undesired yet inevitable in science and engineering. However, by
introducing the engineered noise to the precise solution of Jones matrix elements, we break …

The combination of conventional polarization optical elements, such as linear polarizers and
waveplates, is widely adopted to tailor light's state of polarization (SOP). Meanwhile, less …

Over the last two decades, the capabilities of metasurfaces in light modulation with
subwavelength thickness have been proven, and metasurfaces are expected to miniaturize …

Thirty years ago, Coullet et al. proposed that a special optical field exists in laser cavities
bearing some analogy with the superfluid vortex. Since then, optical vortices have been …

Optically variable devices (OVDs) are in tremendous demand as optical indicators against
