Abstract
An optical coupling system having a split sleeve with a metallized strip adhered to a housing barrel at one end. The sleeve may be smaller than an optical fiber ferrule. The sleeve may have spring-like flexibility and be stretched open at the slit sufficiently to permit insertion of the ferrule in the sleeve. The sleeve may be made of zirconia. The ferrule may be held by the sleeve's spring-like contraction around the ferrule. Attached at the other end of the barrel may be an optoelectronic element such as a vertical cavity surface emitting laser. An optical fiber end of the ferrule may be aligned with the laser. Since the ferrule may be held firmly by the sleeve attached to the coupling barrel, there would be virtually no movement or wiggle of the fiber end relative to the laser and thus the alignment may be maintained.
