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.

Abstract: Methods and devices for handling wafers during wafer processing are provided. One embodiment includes an apparatus for holding a wafer. The holding apparatus includes a pocket for receiving a wafer, and may include a mechanism allowing for the wafer to be secured within the pocket. Methods are also included for preparing a wafer for fabrication processes by the use of a wafer holding apparatus. These methods may include applying a layer of photoresist to the surface of a wafer.

Abstract: A zero-clearance receptacle for single mode optical fiber couplers. The zero-clearance receptacle includes an internally fluted V-groove formed by internally extending legs. The zero-clearance receptacle uses the fundamental action of the V-groove to accurately locate an optical fiber ferrule inserted into the zero-clearance receptacle in the radial direction. The zero-clearance receptacle further includes a slot that receives a biasing element, such as a spring, that biases the optical ferrule against the V-groove legs. This enables accurate positioning of an optical fiber in the optical ferrule relation to an optical element such as a VCSEL or a photoreceptor. The zero-clearance receptacle beneficially fits into an optical coupler, which may have a lens.
