Abstract

We demonstrate experimentally all-optical stabilization of a single-mode laser diode subject to external optical feedback operating in the low-frequency fluctuations (LFF) regime, by the technique of applying a second delayed optical feedback. We interpret our results as suppression of LFF through destruction of the antimodes responsible for the LFF crises and stabilization of the laser through creation of new maximum gain modes, in agreement with recent theoretical predictions.

Experimental optical spectra measured in double-cavity configuration as a function of threshold reduction ΔI2 owing to the second-feedback strength. (a) LFF is observed in the absence of the second feedback. Increase of the second-feedback strength leads to stabilization [(b) and (f)] interspersed with unstable regions [(c)–(e) and (g)]. The optical spectra have been normalized with respect to the maximum of trace (b).
