Gbit / s Lithium Niobate Modulator
As 10 Gbit/s long-distance optical communication systems become more and more pervasive, requirements rise relating to increased levels of performance, as well as the miniaturization of key devices that configure such systems. Lithium niobate (LN) modulators are used primarily as optical modulators that change high-speed electrical signals at 10 Gbit/s to optical signals for long-distance commu...
متن کاملLow temperature synthesis and properties of lithium niobate thin films
Thin flhns of lithium niobate were deposited on silicon ( 100) by a sol-gel technique and were annealed in oxygen at 400 “C. The annealed films were characterized by x-ray diffraction and transmission electron microscopy which showed crystallization to LiNbO,, a preferred orientation of the films, and an average grain size of about 0.5 ym. Electrical characterization of the films in the metal-f...
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 کاملEnhanced electro-optical lithium niobate photonic crystal wire waveguide on a smart-cut thin film.
We report an electro-optically tunable photonic crystal linear cavity etched on a 200 nm lithium niobate waveguide ridge. The photonic crystal cavity and the ridge are both fabricated on a 1 μm thin film of lithium niobate obtained by smart-cut technology. The photonic crystal, of area 4x0.8 μm2, has been engineered to work in a slow light configuration so that the electro-optic effect is 20 ti...
متن کاملSecond 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...
