Abstract
As a result of the application of an optoelectronic feedback on the pump current, the radiation emitted by a semiconductor laser displays high frequency oscillations. A linear stability analysis, based on the rate equations, shows that the feedback intrinsic delay τ introduces a set of resonances in the power spectrum, and each of them can be excited by a suitable choice of the loop gain B.[1] Only low B regimes have been experimentally investigated yielding the excitation of one oscillation near the relaxation frequency Ω of both continuous-wave [1,2] and self-pulsing lasers.[3,4]
