Performance monitoring is one of the key features to
create self-managed optical networks. Monitoring the
characteristics of an optical channel is important
for designing robust and reliable optical
telecommunication system. This book examines the use
of highly integrated ( 500 microns) and low loss (
1 dB) in-fiber taps for monitoring the power and the
wavelength of an optical signal that propagates in
the core of an optical fiber.
The dispersive scattered light from single of
multiple tilted fiber Bragg gratings (TFBG) may be
measured and serve as a monitoring signal. Novel
power and wavelength monitors have been designed and
realized by exploiting this key characteristic.
The power monitor can measure the power of a single
wavelength signal over a bandwidth that can be
adapted by the grating tilt angle. The wavelength
monitor provides both a high wavelength selectivity
(sub-picometer level) and a large operating
wavelength window ( C-band).
The impact of an undesirable variation of the
polarization state of the incident light on the
device performances has been analyzed as well as ways
for compensating it.
