| Abstract: | Analysis of linear chirped Bragg optical fiber grating by piecewise apodised technology bases on the couple-mode theory and the transfer matrix approach. This paper analyses the characters of reflection spectrum and time delay curves with an example of 5 symmetrically apodised grating segments. Comparing the result with traditional technology: whole apodised and symmetrically apodised technology, the study proves the advantages of piecewise apodised method. |
