Bragg gratings have been written in germanium-doped optical fibers that have been treated to remove the UV absorption bands associated with oxygen-deficient defects. When one is using high-intensity 193-nm light from an ArF excimer laser to fabricate the gratings, the refractive index increases and the grating transmission spectra are similar to those obtained in standard (untreated) fiber.
布拉格光栅已写入经过处理以去除与缺氧缺陷相关的紫外线吸收带的掺锗光纤中。当使用来自ArF准分子激光器的高强度193纳米光来制造光栅时，折射率会增加，并且光栅透射光谱与在标准（未处理）光纤中获得的光谱相似。
