Abstract |
Inthis paper, the performance of various apodization profiles (uniform, hyperbolic tangent and
gaussian) for un-chirped Fiber Bragg Grating is investigated. Apodization techniques are used to
get optimized reflection spectra with high side lobe suppression. The simulations are done by
solving coupled mode equations in MATI..AB using transfer matrix method which explains the
relationship between the guided modes. The result shows that Gaussian profile suppresses side lobe
level much more efficiently than uniform and hyperbolic tangent profiles. Gaussian apodized Fiber
Bragg Grating is used to indicate strain by producing wavelength shift.
MATI..AB and Opti-grating result gives an idea about the efficiency of the suggested scheme to
analyze strain measurements by giving a linear response. © 2012 Optical Society of America.
