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.
