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…
