After optimization, we demonstrate a record high nonlinear coefficient d 33 ≈ 1.6 pm/V, a two-fold improvement over highest reported d 33 value in fused silica that we attribute to the presence of germanium.EnglishGermanosilicate filmsSecond-order nonlinearityFilm growthFused silicaGermanium compoundsNonlinear opticsOptical filmsConference Paper10.1109/CLEO.2005.202380
