In this book, we present the unique properties of Hollow-Core Photonic Crystal Fibres (HC-PCFs) for sensing applications in terms of viscosity detection and DNA sensing using a special poly(ethylene) glycol (PEGDA) hydrogel. Thus, we report the characterisation of light propagation within HC-PCFs and the development of a selective filling process with the investigation of a new viscometer device, and a new device for DNA sensing development, and also the chemical process for hydrogel growth was adapted to the fibres. By combining HC-PCFs with the hydrogel we enable 3D volumetric sample grow inside the HC-PCFs, further increasing the interaction between the sample and the optical signal. We also discussed the hydrogel influence on the guidance properties of the HC-PCF; analysed and detected immobilised labelled DNA sample within the hydrogel using the fluorescence techniques. In addition, the suspended-core optical fibres are investigated in terms of integration with the hydrogel and DNA sensing. I hope that the presented work would help working with Photonic Crystal Fibres and simplified understanding of properties of these fibres.
About the author
My research adventure in Photonics has begun in Tyndall National Institute in Cork, Ireland, where I completed my PhD. Before this time I graduated from Wroclaw University of Technology in Poland with a degree in Applied Physics. Currently, I work in Germany on post-doctoral position in Leibniz Institute for Astrophysics.
