Abstract

We have measured the Bragg wavelength shift of three gratings from -30/spl deg/C to +80/spl deg/C. The observed deviation from linearity is a quadratic function of temperature, arising from the non-linear thermo-optic coefficient of silica glass.

光纤光栅温度系数偏离线性

我们测量了三个光栅的布拉格波长从-30/spl°C到+80/spl°C。观察到的线性偏差是温度的二次函数，这是由硅玻璃的非线性热光学系数引起的。
