摘要： A method for producing an externally injected gain switch laser ultrashort pulse, comprising the following steps of ultrashort light pulse signals having multi-longitudinal mode characteristic produced by the gain switch laser are inputted into an optical amplifier and then amplified; a spectral component signal selector selects a narrow spectral component signal outputted by the optical amplifier, the narrow spectral component signal is within an amplified spontaneous emission noise frequency band and its central wavelength is equal to the longitudinal mode of the gain switch laser; a route of the narrow spectral component signal is used as an external seed light and reinjected into the gain switch laser via a spectral component signal feedback loop. Therefore, the oscillation of a selected single longitudinal mode within the cavity of the gain switch laser is enhanced, thereby forming an externally light injected locking.

摘要： A method for producing ultrashort pulses from an external injection gain-switched laser comprises the following steps: inputting an ultrashort optical pulse signal having multi-longitudinal mode spectral characteristic, produced by a gain-switched laser, into an optical amplifier to amplify it; selecting, by a spectral component signal selector, a narrow spectral component signal outputted by the optical amplifier that is within an amplified spontaneous emission noise frequency band and has a central wavelength equal to one of the longitudinal modes of the gain-switched laser; and, using one part of the narrow spectral component signal as an external seed light, which is reinjected into the gain-switched laser via a spectral component signal feedback loop so that the oscillation of a selected single longitudinal mode within a cavity of the gain-switched laser is enhanced, thereby forming external light injection locking, another part of the narrow spectral component signal being used as a required ultrashort pulse.

摘要： The present invention relates to an adaptive and all-optical method for data packet rate multiplication compatible with multiple data rates and/or multiple communication protocols. By performing a real-time pulse width compression on an original electronic or optical packet from an end user or a network interface device, the method generates an optical packet having an identical rate with the original packet while the duration of each pulse being significantly reduced. Then, by eliminating any redundant idle time due to the pulse width compression, the method also shortens data period and thus makes the rate of packet multiplied. The present invention addresses the technical problem of limited data rate in EO/OE conversion as known in the prior art and solves fundamentally the interconnection and communication between networks or systems of different data rates and/or protocols. The method of the present invention thus enables the design of an ultrahigh rate all-optical communication system and network transparent in rate and protocol.
