METHOD FOR MAKING OPTICAL FIBERS METHOD FOR MAKING OPTICAL FIBERS

摘要

Optical fibres whose refractive index profiles show specific peripheral and/or radial and/or axial optical modulation structures are manufactured according to the PCVD method, in which such method parameters are varied which influence: (a) the uniformity of the material transport to the inner wall of the tube and/or the deposition yields of the glass over the tube circumference and/or (b) the axial position of the local deposition zone with respect to the reactor producing the plasma.
