摘要：

An online measurement method for the photosensitivity of fibers is proposed. This method is simple and useful. Theoretical and experimental studies have been carried out. This method is based on the Mach-Zelinder interferometer (MZI). One arm of the MZI is externally exposed to UV light at 248 nm originating from a KrF excimer laser. Then the output optical spectrum is measured, by some relevant analysis, and the photosensitivity of the fiber can be obtained. The relationship between the refractive index increment of fibers and the exposure time is in accordance with the absorbing model that is brought forward by H. Patrick, which shows that this method has high precision. (c) 2007 Elsevier GmbH. All rights reserved.
