Abstract
The coupling phenomena dependence with the lateral separation between the laser stripes in laterally coupled diode lasers is of major importance for the design of these devices as a solution to overcome the intrinsic bandwidth limitation of semiconductor lasers. In this work an experimental study of the coupling dependence with the separation between laser stripes is presented. For that purpose a comparison of the spectrally resolved near and far fields and of the frequency responses obtained with the laterally coupled diode lasers for devices with different separation between the ridges is made.
