Extracting the refractive index profile from near-field mode images of vertical-cavity surface-emitting lasers
In this thesis, a novel method of imaging the near-field intensity patterns of a vertical-cavity surface-emitting laser (VCSEL) is presented. The method is to use an imaging spectrometer to separate closely spaced modes and to image a vertical slice of each profile. The images are then reconstructed...
