A technique for mitigating the effect of the writing-beam profile on fibre Bragg grating fabrication

Research output: Contribution to journalArticle

Abstract

We propose and demonstrate a pre-compensation mechanism to account for the writing-beam profile which when applied to the design of advanced fibre Bragg gratings helps to achieve a desired design spectral response. We use the example of a complex multi-channel grating as an example to demonstrate the improvement achievable using the pre- compensation and find good agreement between experimental results and numerical calculations.
