Thermal Poling of Boron-Codoped Germanosilicate Fibre

The dependence of a linear electro-optic (LEO) coefficient induced into boron-codoped germanosilicate fibre on thermal poling conditions (poling voltage, poling temperature and poling time) has been systematically carried out using a Mach-Zehnder interferometer. The LEO coefficient increases as a ∼2.7 power law with the poling voltage; it can be maximally induced into the silica fibre within a temperature range from 250◦C to 300◦C; it exponentially increases with poling time until saturation but after that it then decreases. Possible mechanisms of thermal poling are discussed in the light of the experimental results. key words: optical communication, communication cable and
