Electro-optic (EO) effect in proton-exchanged lithium niobate: towards EO modulator

摘要

The present work discusses about the modulation of input laser signal using electro-optic (EO) effect in lithium niobate (LN) crystal. EO properties of LN crystal have been studied using Senarmont compensation method. Further, aiming towards the applicability of this technique in thin films, an optical waveguide has been fabricated in proton-exchanged LN (PE-LN) using prism coupling technique. Dynamic variation of the EO coefficient of PE-LN has been studied utilizing an optical waveguide with Senarmont compensation method.
