摘要
The temperature dependence of the strain sensitivity of fibre Bragg gratings written into a number of different fibre types has been investigated. It was found that the strain response changed on average by 0.21 +/- 0.03 fm muepsilon(-1) degreesC(-1) over a range of temperatures between 100-400 degreesC. These results were in agreement with predictions based on material parameters.
