Abstract

In this paper, we utilize the concept of the Wigner distribution function (WDF) on distributed-Bragg-reflector taper lasers (DBR-TPL). The WDF allows the derivation of the phase and the intensity distribution just as well as the spatial coherence properties of the laser beam. For a given single-mode fiber the coupling efficiency for a given beam and optical system can be obtained by means of a simple overlap integral. Simultaneously, this approach delivers the corresponding beam forming requirements to meet the optimum coupling condition. We found a good agreement between the measured coupling efficiencies of the DBR-TPL into a single-mode fiber under varying coupling conditions and the corresponding efficiencies derived from the measured WDF by simulating the same coupling conditions.
