| | It is worth while to explore for simple and compact optoelectronic devices having the all-optical signal regenerating and reshaping functions since it is highly advantageous to bring those functions cost-effectively into the future photonic networks. We have studied the effects of optical injection into a mode-locked monolithic laser diode (MLLD) device of dual optical modes, and found out its digital action, i.e. a sensitive and abrupt optical inverter action which could lead to the regenerating and reshaping functions. Indeed, its static input/output (I/O) curve exhibits extremely abrupt switching characteristics in the μW regime, which look fairly similar to those of inverters in electrical logic circuits. We also confirmed its dynamic action for a 155.52 Mb/s NRZ PRBS data stream. We named this scheme as MIX-PI (photonic inverter based on a monolithic diode laser with injection locking and cross gain modulation(XGM) effects employed) taking its phenomenological and structural aspects into consideration and believe that it is potentially attractive for practical applications in photonic networks. |
