Abstract: A gap fiber Bragg grating (g-FBG) is fabricated by cutting a uniform FBG in the middle to introduce a small air gap between the two sections. Numerical and experimental investigations show that the g-FBG has the characteristics of both a phase shifted FBG and a Fizeau interferometer. The peak transmission wavelength of the g-FBG can be tuned by adjusting the air-gap longitudinally or transversely with respect to the fiber center-axis. With a g-FBG as tunable intra-cavity filter, a tunable fiber ring laser with a narrow line-width is demonstrated. The wavelength tuning range of the laser is 0.12 nm with a output power flatness better than 0.9 dB. The 3 dB spectral line-width is less than 12 pm and output power is 3.68 dBm.
