ABSTRACT:
An apparatus for fabricating optical fiber mode scramblers and optical fiber couplers as an integral part of an optical bus by the utilization of a laser to remove cladding on the optical fiber bus to form the mode scramblers and couplers. An excimer laser is utilized to ablatively remove the cladding which is a polymer material. The optical core is composed of a material which is not readily affected by the excimer laser. The optical bus is fabricated by enclosing an optical fiber in an optical bus assembly. The optical fiber has only cladding and an optical core and has no buffer surrounding the cladding. The optical bus assembly provides for a plurality of optical couplers for removing and adding light to the optical bus and intermixed with the optical coupler are a plurality of optical scramblers.
