Abstract
Four different external resonator concepts including VBGs for spectral stabilization of HPDLs are modelled and numerically evaluated to be compared to each other with respect to stabilization efficiency and sensitivity to the “smile-error". The coupled resonators including the external system and the diode laser are solved with a Fox-Li approach. The paper gives a brief summary about the applied simulation model and proceeds with the results for the different feedback concepts. The effective reflectivity, losses in the optical system, losses due to the back-coupling into the waveguide and the averaged optical confinement factor are calculated.
