Mode-Locking and Solitons in Semiconductors

The MOLOSSE project aims at bridging the notion of temporal cavity solitons in a passive nonlinear optical cavity with semiconductor laser mode-locking.

The project is coordinated by Stephane Barland and funded by Agence Nationale de la Recherche (ANR-12-JS04-0002-01); it started on October 1st, 2012 for a duration of fourty-two months.

The project will grow in close collaboration with the e-buffo project (co-funded by Région Provence Alpes Côte d'Azur and Centre National de la Recherche Scientifique), which aims at exploring the possibility of buffering optical data by leveraging the excitability mechanism.

Both projects will be developed at Institut Non Linéaire de Nice.

phase solitons emerge from chirally charged chaotic areas

One of the main goals of the MOLOSSE project was to explore alternative approaches for the generation of dissipative solitons in relation to mode locking in semiconductor lasers and so we did. In this work, we show that a ring semiconductor laser submitted to coherent external forcing can host dissipative solitons whose existence is fundamentally based on the oscillatory nature of the laser system. Contrary to most optical solitons, the objects we describe host a chiral charge. The stability of only one of the two possible chiral charges results from the broken parity symmetry in a propagative system with non-instantaneous medium.

nucleating dissipative solitons

I am very happy and proud to write that our recent work on excitable systems with delay was published in Nature Communications. Of course I am heavily biased but still, I believe this work is truly interesting in several ways. Of course there is the fact that we demonstrate storage of information in the phase of an optical beam (instead of power), and the fact that we can not only write, but also erase those phase bits. But the way we arrived to these results and the questions they raise are in my view more interesting than the answers they bring.
