Second harmonic generation in nano-structured thin-film lithium niobate waveguides.
Integrated thin-film lithium niobate platform has recently emerged as a promising candidate for next-generation, high-efficiency wavelength conversion systems that allow dense packaging and mass-production. Here we demonstrate efficient, phase-matched second harmonic generation in lithographically-defined thin-film lithium niobate waveguides with sub-micron dimensions. Both modal phase matching...
متن کاملSecond-harmonic generation in periodically-poled thin film lithium niobate wafer-bonded on silicon.
Second-order optical nonlinear effects (second-harmonic and sum-frequency generation) are demonstrated in the telecommunication band by periodic poling of thin films of lithium niobate wafer-bonded on silicon substrates and rib-loaded with silicon nitride channels to attain ridge waveguide with cross-sections of ~2 µm2. A nonlinear conversion of 8% is obtained with a pulsed input in ...
متن کاملNonlinear Susceptibility and Second Harmonic Generation in Proton- Exchanged Lithium Niobate Waveguides
Lithium niobate (LiNbO3) is one of the most commonly used optical crystals because of its excellent electro-optic and nonlinear optical properties. Ease of waveguide fabrication and amenability to periodic poling has made lithium niobate highly attractive for quasi-phase-matched guided wave interactions such as second harmonic generation (SHG) and optical parametric amplification/oscillation [1...
متن کاملHighly efficient second-harmonic generation in buried waveguides formed by annealed and reverse proton exchange in periodically poled lithium niobate.
Efficient three-wave mixing devices have numerous applications, including wavelength conversion, dispersion compensation, and all-optical switching. Second-harmonic generation (SHG) is a useful diagnostic for near-degenerate operation of these devices. With buried waveguides formed in periodically poled lithium niobate by annealed and reverse proton exchange, we demonstrate what is believed to ...
