The never-ending increase of the throughput, together with the
heterogeneity of the services offered in the actual data networks
has fostered over the last decade the development of novel
technology strategies, such as All-Optical Label Swapping (AOLS)
with Subcarrier Multiplexed Label (SCML) and Wavelength Division
Mutiplexed (WDM). These strategies allow for the simultaneously
routing of multiple packets in the optical domain, as well as high
bandwidth, flexibility, scalability and transparency with respect
to the service and data format.

In this context, the thesis proposes, analytically model and
experimentally validates optical structures aiming of generating,
re-writing and detecting by means of SCML optical packets
prefiltering based on an Electro-Optical Modulator (EOM) and Fiber
Bragg grating (FBG). The development of analytical models with the
goal of assessing the quality of both signals involving the SCML
optical packets in terms of the quality factor, eye opening and
extinction ratio, as well as for evaluating the packets as a whole
using the figure of merit FM_SCML has been accomplished. The
models consider structures using a single EOM or two EOMs
parallely combined, as well as the FBG prefiltering based
detection technique. This fact has allowed to evaluate the
goodness of the analyzed structures, as well as identify and
quantify the degradation sources caused by interference among the
signals that involve the packet. Consequently, this fact has paved
the way to the desing of custom FBGs properly tailored for the
purpose of minimizing or even eliminating the mentioned
interferences. A novel strategy for the purpose of reducing the
demanding bandwidth by the SCML optical packets has been proposed
and experimentally demonstrated attending to different
configurations based on the so-called optical parallel combination
structure. Finally, a WDM-SCML AOLS network demonstrator involving
the optical parallel combination and optical prefiltering with
high-performance FBGs based on tandem or array configurations has
been designed and implemented. The demonstrator leads to the
generation, re-writing and detection of SCML optical packets and
enables the evaluation of the packet quality in different points
of the system, as well as the verification as a simultaneous
multi-packet router.
