Abstract
Dielectric optical waveguides are joined using a length of tape. One end of the tape is formed into a loop and the ends of two optical waveguides to be joined inserted into opposite sides of the loop. The diameter of the loop is reduced to such an extent that the waveguides cannot be moved alongside one another. The ends of the waveguides are moved together and the loop drawn tightly around the waveguides and secured in position. The diameter of the loop can be reduced using a pair of juxtaposed rollers. The ends of the waveguides can be secured together by suitable adhesive.
