PintoIn this contribution we report the achievement offiber Bragg gratings exhibiting high temperaturesustainability, resultant from type IIA and a new abnormalexposition regimes, and compare their thermal stability withother gratings obtained from different growth mechanisms,namely type I and IA. It is expected that type IIA and thedesignated as abnormal gratings improve the reliability ofhigh-temperature grating-s...

B. Neto; M. J. N. Lima; A. L. J. Teixeira; R. N. Nogueira; J. L. Pinto; J. R. F. da Rocha; P. AndréWe report a method to realize tunable chromatic dispersion compensation based on chirped fiber Bragg gratings (CFBG). The changes on the CFBG dispersion are achieved by controlling a temperature gradient applied to the grating. A thermodynamic model is presented enabling us to simulate the temperature distribution along the grating lenght. Furthermore, a theoretical approach was de...
