Optical fibre with from multicomponent glass core and silica cladding

摘要

The goal of this work was to construct an optical fibre with a thick core made from multicomponent glass and a thin cladding made from quartz glass. The method to calculate durability of such an optical fibre has been worked out. The fibres with cores from commercially accessible multicomponent technical glasses have been prepared. Partial agreement of quantitative theoretical description with the experimental data has been obtained. Durable structures of optical fibres with numerical aperture of 0.35 have been produced from pyrex glass (core) and quartz glass (cladding).
