    • In a first aspect, the present invention comprises an optical filter comprising a fiber having a core and a cladding and a light-absorbing coating applied onto a portion of the fiber cladding, the coating attenuating loosely bound cladding modes. In another aspect, the invention comprises a fiber amplifier apparatus comprising fibers for delivering pump laser light and for monitoring signal light and at least one photodetector optically coupled to a monitoring fiber, wherein either an optical filter is disposed between a monitoring fiber and a photodetector or at least one of the fibers has a core and a cladding and a light-absorbing coating applied onto a portion of the fiber cladding. A method in accordance with the present invention includes providing an optical amplifier having fibers for delivering pump laser light and for monitoring signal light, and applying a light-absorbing coating onto a portion of one of said fibers.
    • 在第一方面,本发明包括一种光学滤光器,其包括具有芯和包层的光纤,以及施加到光纤包层的一部分上的光吸收涂层,所述涂层衰减松散结合的包层模式。 在另一方面,本发明包括光纤放大器装置,其包括用于传送泵浦激光和用于监测信号光的光纤和至少一个光学耦合到监测光纤的光电检测器,其中光学滤波器设置在监测光纤和光电检测器之间, 纤维中的至少一个具有芯和包层以及施加到纤维包层的一部分上的光吸收涂层。 根据本发明的方法包括提供一种光放大器,其具有用于传送泵浦激光和用于监测信号光的光纤,以及将光吸收涂层施加到所述光纤之一的一部分上。
