Polarization-dependent effects in point-by-point fiber Bragg gratings enable simple, linearly polarized fiber lasers.
Fiber Bragg gratings inscribed with a femtosecond laser using the point-by-point (PbP) technique have polarization dependent grating strength (PDGS) and exhibit birefringence. In this paper we quantify the dependence of these two properties on the ellipticity, position in the core and size of the micro-voids at the center of each refractive index modulation. We demonstrate that the effective mo...
متن کاملThermal properties of fiber Bragg gratings inscribed point-by-point by an infrared femtosecond laser
Direct, point-by-point inscription of fiber Bragg gratings by infrared femtosecond laser had been recently reported. Response of these gratings to annealing at temperatures in range 500C to 1050C is studied for the first time. Gratings inscribed by infrared femtosecond lasers were thermally stable at temperatures up to 900C, representing a significant improvement in comparison with the “common”...
متن کاملSynthesis and characterization of fiber Bragg gratings
This thesis is mainly a study of theoretical issues in the field of fiber Bragg gratings. The synthesis problem of gratings is investigated in detail. This applies to synthesis based on desired, complex spectra in reflection as well as in transmission. In addition, methods for characterization of fiber gratings are proposed. For the synthesis problem of gratings, a genetic algorithm and a layer...
متن کاملFabrication of fiber Bragg gratings with 267 nm femtosecond radiation.
Strong high-quality fiber Bragg gratings with photoinduced refractive-index modulation of more than 10-(3) were written in a Corning SMF-28 fiber, a P(2)O5-doped-core fiber and a pure-silica-core fluorine-doped-cladding fiber by third-harmonic radiation (267 nm, 150 fs and 1.2-1.8x1011 W/cm(2)) of a femtosecond Ti:sapphire laser using a phase mask. We compare the 267-nm photosensitivity respons...
