Abstract

In this paper, a kind of special optical fiber bonding high-temperature aging plan is raised. The armored optical fiber technology is applied to guarantee the long-term stability of the optical properties of the standard instrument itself. The temperature compensation encapsulation technology is adopted for optical fiber grating, that is, the wavelength will remain constant under the standard atmosphere pressure and chamber temperature. It becomes the optical fiber grating sensing wavelength standard instrument. The optical fiber grating standard instrument based upon this kind of new-type structure is tested, and the result has its word that the temperature shift of this optical fiber grating standard instrument after encapsulation is less than 0.5pm/℃. Coupled with the simple temperature control, the wavelength accuracy of the optical fiber grating standard instrument will be controlled below ±1pm and its long-term stability will be smaller than 2pm/℃. Differ from F-P standard instrument, this optical fiber grating standard instrument is one without mechanical device and is purely physical. So, it features more reliable performance and is applicable to mass production. The costs of this kind of optical fiber grating standard instrument is under control and will see an important application in the optical fiber grating sensing technology.
