Gain guiding effect
WebAlthough the gain-guiding effect is quite weak it becomes meaningful for large gain coefficients (g=1 m-1) corresponding to an imaginary index of only around 10-5 [5]. This evidence suggest that first-order perturbation theory is good enough for the derivation of pulse prorogation equation [6]. WebEffect of an active layer thickness on the lateral and longitudinal modes of the gain guiding laser with a tapered stripe structure has been studied. We observed broadening in the linewidth of each longitudinal mode as well as continuous emission spectra for the tapered stripe lasers with the thicker active layer of more than 0.1 ..mu..m.
