MULTICORE CONNECTOR OF OPTICAL FIBER

摘要

PURPOSE:To perform axial alignment at the ends of the connectors with high accuracy and achieve the simplification of connecting work by simultaneously working holes for strand arrays and holes for axial alignment of connectors with high accuracy to a silicon single crystal wafer through etching of semiconductor surface treating techniques. CONSTITUTION:Holes 11 of regular quadrangular pyramid form for optical fiber strand arrays (the sizes thereof are about the sizes slightly larger than the strand diameters) and holes 12 of regular quadrangular pyramid form for axial alignment of the ends of the connectors with each other are simultaneously worked at an equal spacing on the surface of a silicone single crystal wafer 10 through crystal face direction selective etching being semiconductor surface treating techniques. For example, square patterns are formed with a mask material for etching such as of oxide film or the like on the surface of a silicon single crystal wafer and etching is done. Thereby, the holes may be worked in the accuracy of micron order.
