Splicing optic waveguides by shrinkable means

摘要

A mass of dimensionally unstable material in cylindrical form is radially shrunk and confined within an outer sleeve of dimensionally stable material. Two ends of optic waveguides are inserted into a bore provided axially through the unstable material. Upon causing the unstable material to expand radially, the presence of the outer sleeve forces the unstable material to compress and grip radially upon the waveguides, thereby urging them into colinear alignment.
