Conclusion
In conclusion, we have reported that 98.5 % peak power reflectivity fiber Bragg gratings were fabricated in the core of B/Ge co-doped optical fiber using 248 nm KrF excimer laser pulses to irradiate a phase mask. The fiber gratings fabricated by the method described above have negligible sideband and good wavelength selectivity. They can find applications in WDM optical fiber transmission systems, fiber grating external cavity semiconductor lasers, and rearearth-doped fiber lasers. But more efforts are needed to further improve the transmission spectra of the gratings, because the ripple in the short wavelength side is harmful to their use in WDM systems.
