摘要
High-spatial-resolution measurements of axial-stress profiles of UV-irradiated fibers are reported, providing diagnostic information and a technique for the direct observation of UV-written grating structures. Measurements have been made with a spatial resolution of similar to 0.3 mu m, which is capable of resolving detail within the pitch of the gratings. (C) 1999 Optical Society of America.
