Erbium-Doped Lithium Niobate Waveguide Lasers
The recent progress in the field of Ti:Er:LiNbO3 waveguide lasers with emission wavelengths in the range 1530 nm < λ < 1603 nm is reviewed. After a short discussion of the relevant fabrication methods concepts and properties of different types of lasers with grating resonator, acoustooptically tunable Fabry Pérot type lasers and new ring laser structures are presented. key words: integrated opt...
متن کاملLithium vanado(V)molybdate(VI), Li[VMoO6]
Brannerite-type Li[VMoO6] has been synthesized by a solid state reaction route. The V and Mo atoms statistically occupy the same site with mirror symmetry and are octa-hedrally surrounded by O atoms. The framework is two-dimensional and is built up from edge-sharing (V,Mo)O6 octa-hedra forming (VMoO6)∞ layers that run parallel to the (001) plane. Li(+) ions are situated in position with symmetr...
متن کاملCharacterization of erbium doped lithium niobate crystals and waveguides
Optical planar waveguides have been fabricated by the titanium in-diffusion process in lithium niobate crystals activated with erbium ions. The waveguides were studied by m-line technique in order to recover the index profile. The effect of the Ti in-diffusion on the structural and spectroscopic properties of the lithium niobate crystals was investigated by Raman and photoluminescence spectrosc...
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 کاملLi-Rich Li-Si Alloy As A Lithium-Containing Negative Electrode Material Towards High Energy Lithium-Ion Batteries
Lithium-ion batteries (LIBs) are generally constructed by lithium-including positive electrode materials, such as LiCoO2, and lithium-free negative electrode materials, such as graphite. Recently, lithium-free positive electrode materials, such as sulfur, are gathering great attention from their very high capacities, thereby significantly increasing the energy density of LIBs. Though the lithiu...
