采用相位掩模和干涉刻纹相结合的方法，制备了谐振波长在宽可见光谱（维斯）范围内的一阶光纤布拉格光栅。我们使用了一种改进的塔尔博特干涉仪，它提供了很大的灵活性，在布拉格波长，空间光栅长度和反射率。已经生产出最短光栅长度小于1 mm且反射率大于70%的光栅。峰值反射率高达99%，已实现在可见光谱。可见光谱范围内的FBG需要亚100 nm尺度的结构尺寸。潜在的应用是在激光和传感器技术领域。(C)2008 Elsevier B.V.保留所有权利。
Using a combination of phase mask and interferometric inscription technique we have generated 1st order fiber Bragg gratings (FBGs) with resonance wavelengths in a wide range of the visible spectrum (VIS). We use a modified Talbot interferometer which offers great flexibility in Bragg wavelength, spatial grating length and reflectivity. Gratings with shortest grating lengths of less than 1 mm and with reflectivities of more than 70% have been produced. Peak reflectivities of up to 99% have been achieved in the visible spectrum. FBGs in the visible spectral range require structure sizes in the sub 100 nm scale. Potential applications are in the field of laser and sensor technology. (C) 2008 Elsevier B.V. All rights reserved.
