Abstract:
AbstractThis article reviews the optical polarization properties of unstrained and strained GaN films with a nonpolar orientation. In unstrained a -plane GaN films, the A exciton becomes completely linearly polarized perpendicular to the c-axis, whereas the B and C excitons are only partially polarized. In m -plane or a -plane GaN films under anisotropic in-plane compressive strain, all three interband transitions between the three uppermost valence bands and the conduction band can become linearly polarized for sufficiently large strain values. The complete linear polarization can be directly

Conventional imaging techniques can only record the intensity of light while polarization imaging can record the polarization of light, thus obtaining a higher dimension of image information.

The chiral metasurfaces can be equated to a significant radiation source of the Z-type current density under the right circularly polari

Photodetectors are the essential building blocks of a wide range of optical systems.

Chiral 2D perovskites with intrinsic chiral optical activity and superior carrier mobility are promising for next‐generation full‐Stokes polarization detection. So far, most of the chiral 2D metal‐halide perovskite‐based photodetectors suffer from limited discrimination of circularly polarized light due to the high exciton recombination rate in single‐phase perovskite, impeding the accurate measurement for Stokes parameters.
