Ferroelectric Switching in x-cut MgO-doped Thin-Film Lithium Niobate: Implications for Periodic Poling and Domain-Wall Electronics
Niels Staal, Michael Rüsing, Tobias Babai-Hemati +12
Thin-film lithium niobate (TFLN) revives a mature ferroelectric as a wafer-scale platform for integrated photonics and, increasingly, for domain-wall electronics such as nonvolatil…

Optimizing Ultra-Long Continuous Wafer-Scale Periodic Poling in Thin-Film Lithium Niobate
Laura Bollmers, Noah Spiegelberg, Michael Rüsing +3
Periodically poled thin-film lithium niobate (TFLN) crystals are the fundamental building block for highly-efficient quantum light sources and frequency converters. The efficiency…
