摘要	Abstract of the DisclosureDisclosed is a fiber amplifier including a gain fiber anda source of pump power having a wavelength .lambda.p coupled to oneend thereof. A signal of wavelength .lambda.s is introduced into afirst end of the gain fiber, and an amplified signal ofwavelength .lambda.s is coupled from the second end thereof. Thesignal can traverse an undesired secondary path as well as apreferred primary path to the amplifier output. To preventlight of wavelength .lambda.s from traversing the secondary path andthus increasing the amplifier noise figure, the amplifierincludes attenuating fiber means for attenuating that portionof the signal of wavelength .lambda.s that propagates in thesecondary path.
其他摘要	发明内容公开了一种光纤放大器，其包括增益光纤和耦合到其一端的具有波长λp的泵浦功率源。波长为λs的信号被引入增益光纤的第一端，波长为λs的放大信号从其第二端耦合。信号可以遍历不需要的次级路径以及放大器输出的首选路径。为了防止波长λs的光穿过次级路径并由此增加放大器噪声系数，放大器包括衰减光纤装置，用于衰减在二次路径中传播的那部分波长λs的信号。
主权项	A fiber amplifier comprising gain fiber means having an input end and an output end, means for coupling pump power of wavelength .lambda.p from a source to one end of said gain fiber means, input means for introducing a signal of wavelength .lambda.s into the input end of said gain fiber means, said introduced signal traversing a preferred, designated path from said input means through said gain fiber means to the output end of said gain fiber means, whereby an amplified signal of wavelength .lambda.s appears at said output end, a portion of said introduced signal traversing a secondary path through said gain fiber means, that portion of said signal that traverses said secondary path would, if unattenuated, increase the noise factor of said amplifier, and attenuating fiber means for attenuating that portion of said signal that traverses said secondary path to said output end of said gain fiber means.
