An approach to all-optical packet switching is discussed. A single Fabry Perot laser diode can function as an all-optical on/off switch with all-optical header processing, and that an all-optical add/drop node can be used to construct an all-optical ring network. It is observed that the injection-locking property of Fabry Perot laser diodes can be used to perform the three basic functions required to construct an all-optical packet switch. Although the all-optical packet switching capability is still very limited, it may eventually lead to practical all-optical packet-switched networks in the future.
