Linear electro-optic effect in sputtered polycrystalline LiNbO3 films

Abstract

Light guiding and modulation was demonstrated in sputtered LiNbO3 films deposited on glass substrates. We report on films’ exceptionally low attenuation (<2 dB/cm) and the highest electro-optical coefficient reported so far for this kind of film (1.34×10−12 m/V).
