Abstract
The first fiber Bragg gratings were accidentally written
in a Ge-doped silica fiber using a high power argon–ion laser [Hill 1978].
Following this first evidence of photosensitivity in optical fibers, a huge
effort was put into fiber gratings: improving their fabrication (they are
now all externally inscribed), obtaining complex profiles, optimizing their
performance, and incorporating them into devices and systems. On this line,
the last decade was characterized by the birth of an emerging class of fiber
gratings which can be defined as “microstructured fiber Bragg gratings.”
They refer to two main categories: one relies on short period gratings writing
in microstructured optical fibers, whereas the second deals with standard
short period gratings where structural defects at microscale are properly
created within the hosting fiber by postprocessing techniques. This paper
reviews the fabrication processes at the basis of this new technology as well
as its properties and applications. Emphasis will be placed on principles
of operation, technological developments and applications discussing perspectives,
and challenges that lie ahead.
