MONOMODE OPTISCHE TRANSMISSIEVEZEL MET EEN TAPS EINDGEDEELTE VOORZIEN VAN EEN LENS EN WERKWIJZE VOOR HET VERVAARDIGEN DAARVAN.

摘要

A monomode optical transmission fibre (1) is described, having a tapered end portion (5) on which a lens (10) is arranged. This lens is obtained by immersing the fibre end in a transparent liquid material (7) whose melting temperature is lower than that of the fibre materials and whose refractive index is substantially equal to that of the fibre core (2), and by allowing the drop which adheres to the fibre after withdrawal to solidify.
