Resumen: A sine-wave-modulated erbium-doped-fiber laser with an external signal coupled into its cavity has been studied. In particular, an analysis on how the time-dependent laser emission changes as a function of the external signal power has been conducted. Under appropriate working conditions, different bistable behaviors have been found. In some cases, the system behaves as a pilot lamp, which, once activated by the occurrence of a certain event, remains on until reset. For other working conditions, the system behaves as a binary memory whose states can be easily switched.
