Embodiment Construction
[0015] The invention provides an all-optical burst amplifier based on SOA cross gain modulation effect in a burst optical network. The present invention will be described in detail below in conjunction with the accompanying drawings.
[0016] Implementation example
[0017] The present invention provides an all-optical burst amplifier based on the SOA cross gain modulation effect in a burst optical network, such as Figure 4 As shown, the system includes an optical burst input signal 401, a DFB laser 402, a 3-dB coupler 403, an SOA 404, an EDFA 405, and an optical filter 406; wherein, the input burst signal and the continuous optical control signal generated by the local laser are simultaneously input In the SOA, due to the SOA cross-gain modulation effect, the control signal is converted into a burst signal complementary to the original input signal, so the total power of the two becomes basically constant, and the combined signal is input into the EDFA for amplification, wh...
