چکیده
An integrated electro-optic modulator based on a waveguide Bragg grating in thin-film lithium niobate is introduced. The compact device with footprint of 10 × 400 ?m2 displays an optical extinction ratio 53.8 dB at wavelength 1555.9 nm the C-band. With simple intensity modulation and direct detection scheme, data rates up to 100 Gbit/s are demonstrated 2-, 4- 8-level pulse-amplitude formats. filter characteristic suppresses one sideband, resulting inherent single sideband modulation. This enables transmission on-off keying signal over 12 km standard single-mode fiber 1559.05 nm, without need for chromatic dispersion compensation.

Optical characterization of ultra-short Bragg grating on lithium niobate ridge waveguide.
In this Letter, we report a technique to etch giant aspect ratio nanostructures in lithium niobate. An 8 μm long Bragg grating on a Ti:LiNbO3 ridge waveguide was fabricated by combining optical-grade dicing and focused ion beam milling. The reflectivity was evaluated using an optical coherence tomography system: it is measured to be 53% for the TM wave and 47% for the TE wave. We study by 2D-FD...

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 کاملGbit / 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 کاملElectro-optical tunable waveguide Bragg gratings in lithium niobate induced by femtosecond laser writing.
We report the fabrication of femtosecond laser-induced, first-order waveguide Bragg gratings in lithium niobate in the low repetition rate regime. Type-II waveguides are written into an x-cut lithium niobate wafer and structured periodically to achieve narrowband reflections at wavelengths around 1550 nm. Additionally, electrodes are employed to allow for electro-optic tuning of the spectral re...
