An optical apparatus () includes a base member () with a plurality of grooves (), and includes a respective lens () fixedly mounted in each groove. Optical filters () are mounted on the support member in predetermined locations. One such lens is fixedly secured to an input optical fiber (), and the input fiber is used to introduce radiation into the apparatus. Several output optical fibers () are successively positioned in relation to respective lenses by a fiber positioner (), which monitors the amount of radiation passing through the fiber being positioned, and then causes a laser () to fuse the fiber end to the associated lens in a selected position.

Method and apparatus for effecting alignment in an optical apparatus

An apparatus includes a support section which supports a further section, an optically transmissive substrate, and a dispersive section, the further section transporting plural signal components at respective frequencies along a path of travel. A plurality of optical fibers have ends fixedly coupled to a surface on the substrate. The dispersive section has a dispersive characteristic which deviates a direction of travel of each signal component by a respective different amount to optically map each signal component between the end portion of a respective fiber and the path of travel in the further section. During assembly, the fiber ends are moved relative to the surface while radiation passing through them is monitored, and then they are fixedly coupled to the surface in a selected position.
