Theory of the linewidth-power product of photonic-crystal surface-emitting lasers

This paper presents a general theoretical framework for calculating the intrinsic linewidth of photonic-crystal surface-emitting lasers (PCSELs) by modeling spontaneous emission via a classical Langevin force, deriving key parameters like the Petermann and Henry factors, and demonstrating that the theory predicts kilohertz-range linewidths for watt-level output powers in agreement with experimental results.

Evidence of Ultrashort Orbital Transport in Heavy Metals Revealed by Terahertz Emission Spectroscopy

Using terahertz emission spectroscopy on wedge-shaped heavy metal|Ni heterostructures, this study provides the first direct experimental evidence that orbital mean free paths in heavy metals are ultrashort (sub-nanometer scale) and shorter than spin counterparts, confirming that bulk inverse orbital Hall effect governs orbital-to-charge conversion.

Optical vortex generation by magnons with spin-orbit-coupled light

This study demonstrates that the interplay between magnon-induced Brillouin light scattering and optical spin-orbit coupling enables the nonreciprocal transformation of a Gaussian beam into an optical vortex beam by simultaneously breaking temporal symmetry via magnetic ordering and spatial symmetry via light focusing, thereby revealing that magnons can control the total angular momentum of light.
