| All-optical packet switching technology which needn't use photoelectric conversion of light overcome the electronic speed bottleneck. This technology can greatly improves the flexibility of network switching and routing distribution, increases the number of users, achieve network nodes to the automatic identification, so optical packet-switched will be the next strategic objectives of all-optical network .The interaction of two light beams in Fabry-Perot semiconductor laser diode have a large range of applications in all-optical networks and optical logic, such as all-optical ON/OFF switch, all-optical wavelength conversion, all-optical waveform shaping, all-optical flip-flop, all-optical logic device and so on.In this paper, the theory of the interaction of two light beams in Fabry-Perot laser diode has been analyzed, and the usage of the laser diode in all-optical network has been studied .The output power and wavelength stability is fined out to have great impact in its application. Based on the requirements of Fabry-Perot laser diode, the part of laser diode-driven and temperature-controlled has been design. The function of temperature display is firstly used in the making of laser diode. And then some experiments based on FP laser have been investigated theoretically and experimentally, such as the injection-locked and optical bistability have been fined out.Finally, a non gate which is based on Fabry-Perot laser diode is proposed , which can be use to a 2.5Gb/s date signal, and the extinction ratio is 8dB. The advantage of this system is simple structure and can be integrated easily. This model has important guidance meaning and reference value to the future research of All-optical flip-flop. |
