Abstract
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.
