Abstract

PURPOSE:To obtain a high binding efficiency without giving substantial loss to a main signal line by providing a round ball or an elliptical body of rotation of a rotation of a transparent dielectric material in an optical communication fiber having a suitable curvature and by injecting light into the dielectric material from the outside.
