Ultra-broadband adiabatic light transfer in titanium diffused lithium niobate waveguides

摘要

Ultra-broadband adiabatic light transfer was demonstrated for the first time in lithium niobate. Coupling bandwidths and efficiencies of ~540 nm and >0.96, respectively, were obtained with 5-cm long Ti:LiNbO3 adiabatic couplers for both polarization modes.
