Photon-Sphere Modes in Curved Optical Microcavities: A Black-Hole Analogue Laser. [PDF]
Adv Sci (Weinh)An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling
