A sub-volt near-IR lithium tantalate electro-optic modulator
Keith Powell, Dylan Renaud, Xudong Li +4
We demonstrate a low-loss integrated electro-optic Mach-Zehnder modulator in thin-film lithium tantalate at 737 nm, featuring a low half-wave voltage-length product of 0.65 V$\cdot…

Robust Poling and Frequency Conversion on Thin-Film Periodically Poled Lithium Tantalate
Anna Shelton, C. J. Xin, Keith Powell +4
We explore a robust fabrication process for periodically-poled thin-film lithium tantalate (PP-TFLT) by systematically varying fabrication parameters and confirming the quality of…
