Abstract: Metasurfaces have the capability to boost the generation of distinct colors by improving the interaction between surface materials and photons. We present a straightforward and polarization-tunable aluminum nitride metasurface. This metasurface enables the display and… read more here.

Abstract: Laser geometric modes with switchable orthogonal polarization are explored in a c-cut Nd:YVO4 laser with a symmetric concave-convex resonator under both continuous-wave (CW) and passively Q-switched (PQS) operation. By leveraging birefringent thermal lensing to separate… read more here.
