Measurement of photo-induced birefringence in germanosilicate fibers
In this paper, we report a novel method for accurately measuring the photo-induced birefringence of germanosilicate fibers by using an all fiber Mach–Zehnder interferometer. The results indicate that the photo-induced normalized birefringence of C598-302(s) germanosilicate fiber can attain 10-5 and is multi-decaying-exponentially proportional to the UV exposure.
