Paper Abstract

A method for fabricating glass exposed-core microstructured optical fibre is demonstrated. This fibre design consists of a jacketed suspended optical nano/micro-wire that is partially exposed to the external environment, which is particularly useful for sensing. These fibres allow for strong evanescent field interactions due to the small core size, while also providing real-time and potentially distributive measurements. We compare experimentally the exposed-core fibre and an equivalent enclosed-core microstructured fibre in terms of their performance as evanescent field sensors, and demonstrate that the exposed-core fibre can provide at least an order of magnitude faster measurement response time.
