摘要
In this letter, based on the proposed concept of Moire sampled Bragg grating (SBG), the equivalent chirp rates of various Fourier orders in a sampled Bragg grating with chirp in the sampling period (CSP) is demonstrated for the first time via a simple novel experimental method using phase mask rotation and dual exposure technique. Difference between experimental data and calculated results is less than 9%.
