Abstract
A dielectric optical waveguide joint in which first and second dielectric optical waveguides are located end to end in a groove in a plate of non-ductile material. The dielectric optical waveguides are retained in the groove by a mass of ductile material which has been formed so as to flow into intimate contact with the plate and the first and second waveguides. The invention also provides a method of forming a waveguide joint.
