Optically variable devices (OVDs) are in tremendous demand as optical indicators against
the increasing threat of counterfeiting. Conventional OVDs are exposed to the danger of …

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

Based on the 3D Dirac semimetals (DSM) supported tilted double elliptical resonators, the
tunable propagation properties of quasi-bound in continuum (BIC) resonance have been …

Optical sensors, with great potential to convert invisible bioanalytical response into readable
information, have been envisioned as a powerful platform for biological analysis and early …

Electro-optic modulators are essential for sensing, metrology and telecommunications. Most
target fiber applications. Instead, metasurface-based architectures that modulate free-space …

Metasurfaces have been rapidly advancing our command over the many degrees of
freedom of light; however, so far, they have been mostly limited to manipulating light in free …
