Virtual draw model for tubular anti-resonant hollow core fibres

Presented at Frontiers In Optics this week is an analytical model to predict the fabrication parameters and fibre geometry for hollow core anti-resonant tubular fibres. Such a model can identify the parameters for the draw to improve efficiency, and can check the feasibility of given geometry. The model also helped identify dynamics that occur within the furnace otherwise hidden to the fabricator.

Virtual draw model for tubular anti-resonant hollow core fibres

A numerical model that accurately predicts the fabricated geometry of tubular hollow-core fibers is presented and experimentally validated. Such a model can be invaluable in driving design decisions for yield upscaling and loss reduction.
