N2 - Erbium doped integrated waveguide amplifier based on thin film lithium niobate on insulator (LNOI) is fabricated using photolithography assisted chemo-mechanical etching technique (PLACE). A thin cladding layer of tantalum pentoxide (Ta2O5) is deposited on the fabricated LNOI waveguide which boosts the small-signal internal net gain exceeding 20 dB. Experimental characterizations reveal the advantage of Ta2O5 cladding in higher optical gain compared with the amplifier without cladding. The demonstrated high-gain LNOI amplifier holds great promise in lightwave communication, optical sensing and metrology.
