Abstract
A star coupler is described in which a plurality of optical fibers are embedded in a first rigid substrate. The fibers may be etched or polished to a core area to expose a first evanescent coupling zone. A second substrate has one or more optical fibers embedded in the second substrate. The optical fibers in the second substrate are similarly etched or polished to expose a second evanescent zone area. The two substrates are then placed in juxtaposition with each other so that the first and second evanescent zones are in close proximity to one another so that evanescent coupling may occur between the plurality of fibers in the first evanescent zone and one or more optical fibers in the second evanescent zone.
