Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings

Advanced Photonics Research, EarlyView.
The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...

Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces

Advanced Photonics Research, EarlyView.
The spatially varying vortex beams with the customizable propagation trajectory and the controllable topological charge evolution are demonstrated using the Sb2Te3‐based plasmonic metasurfaces. Benefiting from the dispersion‐free property of the Pancharatnam–Berry phase and the broadband response of polarization conversion efficiency of the nanobrick ...

Numerical Study on the Potential Enhancement of Organic Terahertz Sources through Tilted Pulse Front Pumping

Advanced Photonics Research, EarlyView.
In this article, two individually successful concepts, the tilted pulse‐front pumping technique and organic terahertz crystals for highly efficient THz generation are combined in the framework of numeric calculations resulting in increased conversion efficiency, increased damage threshold, and extended lifespan for ≈2 μm pumping.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, EarlyView.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
