Paper Abstract

The Interpolation method for identification of the Apodized and Chirped Fiber Bragg Gratings is used. For this purpose, the Riccati equation for obtaining the reflection coefficient is used and numerically solved. Then for various system parameters, the maximum reflection peaks, bandwidth of the reflection coefficient and the central frequency are determined. Then using interpolation technique, three analytical equations can be extracted for the above-mentioned quantities. Therefore using the obtained reflection coefficient there is a map from the reflection coefficient in frequency domain to real space (index of refraction space). Hence, for the measured reflection coefficient, one can determine the index of refraction profile including Apodized and Chirped functions. The proposed method is effective and can easily determine the index of refraction profile.
