【Abstract】 In this paper, a compact temperature- compensated fiber grating package is proposed. The package comprises two materials with different thermal expansion coefficients. The releasing strain can compensate the temperature dependent drift of the Bragg wavelength over the range from - 20-40℃. The total variation in wavelength is less then 0.12 nm, 1/6 of the uncompensated fiber grating.更多还原
