FBGs are key components for a vast number of
applications in optical communications, microwave
photonics systems and optical sensors. This book is
about FBGs applications in direct microwave optical
filtering and high speed switching. A comparison is
made between the extensively researched incoherent
optical filters and a technique based on a direct
spectral filtering of microwave signals transmitted
optically. The example of a double-peaked
superimposed FBG used in reflection is analysed to
illustrate the latter technique, which can be used in
RoF systems. The main focus of the book is on
research of a new class of photonic devices, where
gratings are rendered active in fibres with internal
electrodes. Electric control of light in fibres is
exploited in dynamic measurements in the nanosecond
regime. Numerical simulations give accurate
description of the physics behind the birefringence
switching process. Such grating devices have
potential application in Q-switched fibre lasers and
other fields, and are bound to be widely exploited in
the near future. This book will be of special
interest for professionals or researchers working on
RoF systems and photonic devices.
