Hollow core photonic bandgap fibers for gas sensing applications: Progress and current challenges
Hollow core photonic bandgap fibers for gas sensing applications: Progress and current challenges
Hollow core Photonic Bandgap Fibers (PBGFs) enable new concepts for fiber-based sensor devices. In this paper, we review the current status of their application in the area of gas sensing, focusing in particular on two as yet open challenges. Firstly we discuss the issue of gas access and present recent improvements of a femtosecond laser machining technique, which allowed us to achieve cells with multiple side access channels and low additional loss. Furthermore we analyze the impact of modal properties of PBGFs on the performance of practical sensor devices, and we address the issue of controlling the modal properties of these fibers.

Abstract
Hollow core Photonic Bandgap Fibers (PBGFs) enable new concepts for fiber-based sensor devices. In this paper, we review the current status of their application in the area of gas sensing, focusing in particular on two as yet open challenges. Firstly we discuss the issue of gas access and present recent improvements of a femtosecond laser machining technique, which allowed us to achieve cells with multiple side access channels and low additional loss. Furthermore we analyze the impact of modal properties of PBGFs on the performance of practical sensor devices, and we address the issue of controlling the modal properties of these fibers.
