Homotopic Vortex Lasing Mediated by a Resonant Geometric Phase in a Bound States in the Continuum Cavity

Geometric phases are fundamental to wave physics and underpin a broad range of optical phenomena. The most prominent example, the Pancharatnam–Berry (PB) phase, originates from polarization evolution during wave propagation. In contrast, geometric phases associated with optical resonances and cavities remain largely...
