Abstract
Here, we present an innovative preform manufacturing technique for specialty optical fibres based on a carbon monoxide laser heating a rotating preform. The setup performance is evaluated with the aid of finite element modelling. The fabrication process is described in detail using silicon core preforms as a benchmark. The hybrid material nature of such a preform is addressed, together with the relevant characteristics, such as the difference in thermal conductivity and thermal expansion. Si-core preforms with a wide range of core sizes were manufactured, proving the viability of this system for the development specialty optical fibres based on novel materials.
