Chiral lasing via broken parity-time symmetry in bound-state-in-the-continuum metasurfaces
Matthew Parry, Daria A. Smirnova, Andrey A. Sukhorukov +1
We propose a concept for chiral lasing from planar metasurfaces that obviates the need for traditional out-of-plane symmetry breaking by exploiting spatial gain-loss modulation to…

Multipolar second-harmonic generation from high- quasi-BIC states in nanoresonators
Irina I. Volkovskaya, Lei Xu, Lujun Huang +2
Multimode interference and multipolar interplay govern functionalities of optical nanoresonators and nonlinear nanoantennas. Recently, excitation of the high-quality supercavity mo…
