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 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 کاملErbium-implanted high-Q silica toroidal microcavity laser on a silicon chip
Lasing from an erbium-doped high-Q silica toroidal microcavity coupled to a tapered optical fiber is demonstrated and analyzed. Average erbium ion concentrations were in the range 0.009–0.09 at. %, and a threshold power as low as 4.5 mW and an output lasing power as high as 39.4 mW are obtained from toroidal cavities with major diameters in the range 25–80 mm. Controlling lasing wavelength in a...
متن کاملChip-scale cavity optomechanics in lithium niobate
We develop a chip-scale cavity optomechanical system in single-crystal lithium niobate that exhibits high optical quality factors and a large frequency-quality product as high as 3.6 × 1012 Hz at room temperature and atmosphere. The excellent optical and mechanical properties together with the strong optomechanical coupling allow us to efficiently excite the coherent regenerative optomechanical...
