Abstract
In this paper, the coating of optical Bragg gratings with nanocrystalline diamond, obtained by hot filament chemical vapor deposition (HFCVD), is described. Due to the high temperature coating process, uniform fiber Bragg gratings (FBG) were erased during the diamond deposition. However, in the case of regenerated fiber Bragg gratings (RFBG), although attenuated, the optical signal is maintained. The results of the thermal and mechanical characterization of diamond coated RFBG (D-RFBG) suggest that they may be an important tool in the sensing field, including monitoring of high temperatures under harsh environments.
