Abstract
A new method for determining gain spectra is presented. The amplified spontanous emission is measured and spectrally resolved in both TE and TM polarisations; it is dependent on the current injected into the contact stripes of variable length on the laser structures. The maximum gain and internal losses correspond well with the results of broad area lasers.Keywords
