On-Chip Integrated Yb³⁺-Doped Waveguide Amplifiers on Thin Film Lithium Niobate

We report the fabrication and optical characterization of Yb³⁺-doped waveguide amplifiers (YDWA) on the thin film lithium niobate fabricated by photolithography assisted chemo-mechanical etching. The fabricated Yb³⁺-doped lithium niobate waveguides demon...
