In particular, for large pumping the system has a bistable regime in which two stationary quasiunidirectional counter-propagating modes coexist. Bistability is induced by cross-gain saturation of the two counter-propagating modes being stronger than the self-saturation and can be used for data storage when the semiconductor ring laser is addressed with an optical pulse. In this work we study the response time when an optical pulse is injected in order to make the system switch from one mode to the counter-propagating one. We also determine the optimal pulse energy to induce switching. ; This work has been funded by the Spanish MEC and Feder under project TEC2006-10009/MIC (Conoce 2) and FIS2004-00953 (PhoDeCC), by the European Community under projects IST-2005-34743 (IOLOS) and IST-2005-34551 (PICASSO), and by the Balear Government under project PROGECIB-5A (QULMI).
