Low cost optical fibre based Fabry Pérot strain sensor production

The production of Fabry-Pérot based optical fibre sensors has long been an iterative and labour intensive process. This paper demonstrates the production of Fabry-Pérot based optical fibre strain sensors using chemical etching techniques. Utilising hydrofluoric acid (HF) and singlemode optical fibre...

description	The production of Fabry-Pérot based optical fibre sensors has long been an iterative and labour intensive process. This paper demonstrates the production of Fabry-Pérot based optical fibre strain sensors using chemical etching techniques.

These etched fibre ends were then spliced together successfully to form enclosed Fabry-Pérot cavities between 18 and 60 μm in length.
