Mode‐dependent Far‐field Radiation of Circularly Polarized Light by a Single Plasmonic Nanohelix
The numerical simulations explored the chiroptical response and far‐field radiation behaviors of single plasmonic nanoantennas transitioning into helical structures. This study highlights the ability of these plasmonic nanohelices to regulate the far‐field directionality of radiation power and circular polarization in plasmon‐exciton coupled systems ...

A metal‐based thermal metasurface supporting bound states in the continuum is demonstrated and experimentally shown to achieve a record‐high quality factor of 202 and high emissivity of 0.82. The design offers thermally stable, narrowband mid‐infrared emission, making it ideal for high‐precision gas sensing applications.

All‐solution‐processed spin‐LEDs based on colloidal Fe3O4 nanoparticles and CdSe/CdZnS core/shell CQWs that allows for polarization modulation of electroluminescence are fabricated. With these devices, electrical injection of spin‐polarized carriers from the Fe3O4 nanoparticle layer into the CdSe/CdZnS CQWs is demonstrated, realizing circularly ...

A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...
