Inventor: ZHANG B BARRY
IPC: G02B6/26
Filed: 1999-10-19
Abstract: A multiport isolator provides optical isolation between pairs of optical fibers (202, 204; 222, 224) so that light may pass from a first fiber (202, 204) to a second fiber (224, 222) of the pair, but not from the second fiber to the first fiber. The multiport isolator has first and second coupling modules (200, 220) to couple light from different fibers, and an isolator module (410) between the coupling modules to prevent light from passing from the second fiber to the first fiber of a fiber pair. Each coupling module (200, 220) comprises two focusing elements (206, 208; 226, 228) arranged such that the first focusing element (206, 226) direct the beams to intersect the module optical axis and the second focusing element (226, 228) parallelizes the light beams from the first focusing element. The isolator comprises a Faraday rotator (414) interposed between two birefringent plates (412, 416).
