متن کاملErbium-doped Lithium Niobate waveguide lasers: recent progress
Erbium diffusion doping of LiNbO3 (e.g. 30 nm / 1130 °C / 150 hrs) is the preferred method to fabricate an excellent laser material for integrated optics. After Er-doping single mode channel waveguides are defined by the standard indiffusion technique of Ti-stripes. By optical pumping at λ = 1480 nm a wavelenth dependent gain of up to 2 dB/cm is achieved (1530 nm < λ < 1610 nm). Different types...
متن کاملHeterogeneous lithium niobate photonics on silicon substrates.
A platform for the realization of tightly-confined lithium niobate photonic devices and circuits on silicon substrates is reported based on wafer bonding and selective oxidation of refractory metals. The heterogeneous photonic platform is employed to demonstrate high-performance lithium niobate microring optical resonators and Mach-Zehnder optical modulators. A quality factor of ~7.2 × 10⁴ is m...
متن کاملCalligraphic poling of Lithium Niobate.
We demonstrate a novel technique for instituting complex and arbitrary shaped micron-scale domain patterns in LiNbO3 at room temperature. Fabrication of continuous domains as narrow as 2 microm across and hexagonal patterns of the same order accompanied by real time visualization of the poling process are presented.
متن کاملFrequency doubling of femtosecond erbium-fiber soliton lasers in periodically poled lithium niobate.
We report efficient frequency doubling of passively mode-locked femtosecond erbium-fiber lasers. Quasi-phase-matched second-harmonic generation in periodically poled lithium niobate is used to generate 8.1 mW of 190-fs (FWHM), 90-pJ pulses at 777 nm with a conversion efficiency greater than can be obtained with existing birefringently phase-matched nonlinear materials. A dispersion-compensation...
