Fiber-coupled microsphere laser.
We demonstrate a 1.5-microm - wavelength fiber laser formed by placement of glass microsphere resonators along a fiber taper. The fiber taper serves the dual purpose of transporting optical pump power into the spheres and extracting the resulting laser emission. A highly doped erbium:ytterbium phosphate glass was used to form microsphere resonant cavities with large gain at 1.5microm . Laser th...
متن کاملHighly efficient hybrid fiber taper coupled microsphere laser.
A novel hybrid fiber taper is proposed and demonstrated as the coupler in a microsphere laser system. The pump wave and the laser emission, respectively, are more efficiently coupled to and from the sphere modes with this taper structure. A 980-nm pumped erbium-ytterbium codoped phosphate microsphere laser is demonstrated in the 1550-nm band. As much as 112microW of single-frequency laser outpu...
متن کاملChalcogenide glass microsphere laser.
Laser action has been demonstrated in chalcogenide glass microsphere. A sub millimeter neodymium-doped gallium lanthanum sulphide glass sphere was pumped at 808 nm with a laser diode and single and multimode laser action demonstrated at wavelengths between 1075 and 1086 nm. The gallium lanthanum sulphide family of glass offer higher thermal stability compared to other chalcogenide glasses, and ...
متن کاملErbium-implanted silica microsphere laser
Spherical silica optical microresonators were doped with erbium ions by ion implantation at energies of 925 keV and 2.05 MeV using a rotating stage. After thermal annealing at 800 C, light was coupled into the microsphere using a tapered optical fiber. An optical quality factor as high as 1.9 · 10 was observed at k = 1450 nm, corresponding to a modal loss of only 0.01 dB/cm. When pumped at 1450...
متن کاملDesign of fiber coupled Er3+: Chalcogenide microsphere amplifier via particle swarm optimization algorithm
A mid-IR amplifier consisting of a tapered chalcogenide fiber coupled to an Er3þ-doped chalcogenide microsphere has been optimized via a particle swarm optimization (PSO) approach. More precisely, a dedicated three-dimensional numerical model, based on the coupled mode theory and solving the rate equations, has been integrated with the PSO procedure. The rate equations have included the main tr...
