Analysis of tuning of Bragg wavelength of photowritten fiber Bragg gratings during the inscription process using a biprism.

This paper presents an analysis of a simple biprism-based technique that enables inscription of multiple fiber Bragg gratings (FBGs), each with different Bragg wavelength, into a section of an optical fiber. The method offers a tuning range for Bragg wavelength that is comparable to that of the multiple mirror interferometer method. This has an additional… CONTINUE READING
