摘要	A high power (HP) fiber circulator is configured with a case enclosing a plurality of optical components which are arranged so as to define multiple ports. The fiber circulator further includes a plurality of launching and receiving fiber components each of which has spliced delivery and pigtailed passive fibers selectively coupling a HP input signal into and receiving a HP output signal from respective input and output ports. The passive fibers of each fiber component have respective protective coatings spaced from one another and each covering the cladding of the fibers. A light stripper, extending between the protective coatings, is operative to substantially remove cladding-supported light from one of the passive fibers before it reaches the protective coating of the other passive fiber. At least one of the ports includes a wavelength selective component configured to direct the HP input light beam along the desired path between the ports and including a fiber Bragg grating, volume Bragg grating or a combination of these.
其他摘要	高功率（HP）光纤环行器配置有包围多个光学部件的壳体，所述多个光学部件布置成限定多个端口。光纤环行器还包括多个发射和接收光纤部件，每个部件具有拼接传送和尾纤无源光纤，选择性地将HP输入信号耦合到各个输入和输出端口并从其接收HP输出信号。每个纤维组分的无源纤维具有彼此间隔开的各自的保护涂层，每个保护涂层覆盖纤维的包层。在保护涂层之间延伸的光剥离器可操作以在其到达另一无源光纤的保护涂层之前基本上从其中一个无源光纤移除包层支撑的光。至少一个端口包括波长选择部件，其被配置为沿着端口之间的期望路径引导HP输入光束，并且包括光纤布拉格光栅，体布拉格光栅或这些的组合。
