ABSTRACT:
Novel embodiments and manufacturing methods for optical fiber connector plugs and sleeves are disclosed, in which precision holes are fabricated through a thin slab, preferably using preferential etching technique on a semiconductor wafer, such as silicon or gallium arsenide. The angle of the slope is specific in the preferentially etched through-holes. Optical fibers are inserted into the V-shaped through-holes, with the orientation perpendicular to the surface of the slab. The edges of the slab may be sloped at the same slope angle of the through-holes. The same technique can be used to fabricate a sleeve with a twin V-square recess with the same slope angle on the both ends. Since the slope angles are all same and specific, precisely-fitting through-holes, plugs, and sleeves may be fabricated for single-fiber connection and array connection.
