A new package for thermally compensating a fiber Bragg grating, which requires less accuracy in positioning the fiber onto the device, is discussed. Experiments show that it can reduce the shift in reflected wavelength from 1575 pm to 78 pm for a temperature change of 120 K. The deformation of the package showed no hysteresis, and the effective thermal compensation is repeatable over many cycles. Furthermore the package also has the potential to give non-linear thermal compensation for fiber Bragg gratings.
