Record-high positive refractive index change in bismuth germanate crystals through ultrafast laser enhanced polarizability
Unlike other crystals, the counter intuitive response of bismuth germanate crystals ([Formula: see text] , BGO) to form localized high refractive index contrast waveguides upon ultrafast laser irradiation is explained for the first time. While the waveguide formation is a result of a stoichiometric...
