Abstract
Apodized linearly chirped Bragg grating (CFBG) filters have been studied
with a view of determining an optimal set of grating parameters to design
and fabricate linear edge filter for Bragg grating sensor demodulation. A
rigorous numerical computation towards understanding the relation of all the
grating parameters with filter characteristics like the linear bandwidth and
slope efficiency produced some simple empirical formula for the design of
edge filters of specific desired characteristics. The results are corroborated
with experiments.
