Abstract

Single-mode fiber is rapidly becoming the medium of choice for lightwave communications systems carrying long distance terrestrial and submarine traffic as well as local distribution and local area networks traffic. Widespread and convenient utilization of single-mode fibers requires reliable and reasonably priced hardware such as low-loss backplane and field connectors, laser-fiber couplers, and directional couplers. The main drawback of single-mode fibers, which makes fabrication of these components difficult, is their small core size, on the order of 5-10μm. All hardware constructed from and for these fibers, where two cores or light source and core have to be aligned, are inherently very sensitive to axial and transversal displacements as well as to tiny dust particles. These displacements can be induced mechanically or thermally, while the dust comes from just routine handling.
