  • Burst mode rare earth-doped fiber amplifier
    Patent number: 9019591
    Abstract: It is an object of the present invention to provide a rare earth doped fiber whose transient response is suppressed and an optical amplifier for optical packet communication having a good characteristic even if there is little traffic. The above-mentioned problem is solved by an optical amplifier for optical packet communication comprising a first rare earth doped fiber (EDFA) having an active region whose diameter is between 3.4 ?m and 10 ?m, inclusive, an intermediate gain equalizing filter, and a second EDF, wherein the first EDFA is shorter than the second EDFA, and wherein the intermediate gain equalizing filter adjusts the intensity of each wavelength channel so as to equalize the light intensity of each wavelength channel having transmitted through the second EDF.
