Abstract

A detailed theoretical and experimental investigation of incorporation of titanium dioxide into a silica glass preform for making of Ti doped optical fibre by the modified chemical vapour deposition process is presented. Such detailed investigation about incorporation of titanium into a silica glass was done with emphasis on its importance in increasing the refractive index of silica glass optical fibre for use as a radiation sensor in fibre optic dosimeters. Selection of the proper proportions of the supplied reagents TiCl4, O-2 and He in the inlet gas mixture was found to be very much important in order to achieve a desired profile of Ti doped fibre made by the MCVD process. The chemistry of titanium incorporation in silica glass has been thoroughly discussed with regard to thermodynamic data by selection of the proper proportions of the precursor reagents TiCl4, O-2 and He in the inlet gas mixture and studied the effect of deposition temperature.
