Paper Abstract
In this work, we propose a novel fabrication method as technological assessment for the development of microstructured
fiber Bragg gratings (FBGs) tailorable for specific applications. Micro-structured FBG (MSFBG) relies on the
localized stripping of the cladding layer in a well defined region in the middle of the grating structure leading to the
formation of a defect state in the spectral response. The key feature of this class of devices is the strong dependence of
the defect state generated in the grating spectrum on the optical properties of the medium surrounding the device. In fact,
this property enables the development of tunable devices as well as in fiber refractometers and chemical sensors. One of
the main drawbacks of these devices is the fabrication process requiring a well precise control of the stripped region
dimensions. Here, we demonstrate that the optimization of this device is possible by adopting a fabrication process based
on polymeric coatings and UV laser micromachining. These method combined with wet chemical etching allows the
easy prototyping of MSFBGs with the desired features for specific applications.
