Thermal stability and temperature response are very important parameters for fiber Bragg gratings (FBG) to be used as sensors in high temperature applications. Experimental and theoretical analysis of the thermal erasure dynamics and temperature response of FBGs written in hydrogen-loaded and non hydrogen loaded photosensitive fibers has been carried out in the present investigation. The sensitivity and the behavior of wavelength shift of the gratings over the temperature range of 35°C to 1075°C are studied and reported. The regenerative property and anomalous behavior of the gratings were also studied.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
