Dl. Boiko et al., Spectrum of vertical-cavity surface-emitting lasers: linewidth properties and non-degeneracy of relaxation oscillation frequencies, J OPT B-QUA, 3(2), 2001, pp. S166-S172
We give an analysis of the spectrum around the laser line of vertical-cavit
y surface-emitting lasers. We show that they contain sidebands which are no
t symmetrically located on each side of the laser frequency and that this a
symmetry corresponds to a non-degeneracy of relaxation oscillations of the
carriers, A model which explains this non-degeneracy is introduced.
