Void Engineering in Silica Glass for Ultralow Optical Scattering Loss

Optical losses in silica glass fibers remain a challenge their applications. The main contributor to optical attenuation is Rayleigh scattering. This review discusses the recent studies and findings on voids effects loss. Through experimental of pressure-quenching at melting temperature, void size shrunk, loss was reduced approximately half that conventional 0.2 GPa. Our modeling results predicted further reduction expected, credited optimization network, called topological pruning, under high compressive pressures up 4
