Unprecedented Electro‐Optic Performance in Lead‐Free Transparent Ceramics

This is the authors' abstract. We don't add key points for this paper.

A high-performance lead-free electro-optic (EO) transparent material is introduced and used in an EO device operating up to 10 kHz. The BZT–BCT ceramic, named as BXT, has an effective DC EO coefficient, rc = 530 pm V−1, which is higher than state-of-the-art materials such as LiNbO3. The high EO response can be leveraged for miniaturization and/or reduction of the operating voltage of EO devices.
