Dispersive fiber-optic interferometer with extended probing depth

Abstract

We construct a dispersive interferometer based on chirped fiber Bragg gratings(CFBG) and demonstrate improved ranging characteristics. By using a CFBG as a dispersive medium in the reference arm, it was possible to range up to 1 cm, which is beyond the theoretical depth range of 5.8 mm given by both the CW broadband source and the spectrometer. The theoretical background as well as the experimental results will be presented. By using the suggested method, it is expected to be an alternative for extending the depth range of the existing SD-OCT system.
