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…
