Electron-Lattice Synergistic Coordination for Boosting the Electro-Optic Response of the Crystal.

ABSTRACT: The electro-optic (E-O) response is fundamental where the refractive index of materials can be modulated by the external electric field. Up to now, E-O modulation has become a critical technology in photonics, quantum optics, modern communication, etc. However, the design of E-O crystals with broadband availabilities and large E-O effect is still challenging since the E-O response is contributed by both electrons and phonons. Here, an electron-lattice synergistic coordination strategy is proposed for boosting the E-O response, and with the langasite as the subject, a novel crystal La₃Zr_0.5Ga₅Si_0.5O₁₄ (LZGS) is designed. By the rational introduction of the Zr⁴⁺ ion in the octahedral site, it is found that the E-O response can
