Fiber-coupled microsphere laser [PDF]
Optics Letters, 2000 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.

Fiber Coupling to Polarization‐Maintaining Fibers and Collimation [PDF]
PhotonicsViews, 2020 AbstractA stable measurement setup is fundamental for any successful measurement. A major cause of frustration and error is the need to continuously readjust optomechanical equipment because of continuous instabilities. But first decisions have to be made about which components to use. Detailed measurements of fiber parameters like e.g.
