We report here the experimental realization of Fiber Bragg Gratings (FBG) of desired specifications in different application-types of in-house fabricated silica optical fibers, namely, standard telecom fiber of type SM-28, Er3+-doped SiO2–GeO2 fiber and photosensitive high GeO2 fiber. Fibers for this purpose were fabricated by customizing the process variables of the Modified Chemical Vapor Deposition (MCVD) technique used for our laboratory fabrication of optical fibers. To check the performance of the drawn fibers in terms of FBG characteristics, gratings were written by exposing a short length of fibers to interference fringes derived from a frequency-doubled Ar-ion laser using a modified two-beam interferometer system in single phase-mask configuration. Results of inscribing selected wavelength FBGs demonstrate the efficacy of our approach in achieving, reproducibly, high-quality FBGs in all application-fibers.
