摘要：

The authors demonstrate sampled gratings in germanosilicate planar waveguides with multiple, equally spaced reflection peaks of high visibility. Sampled gratings with a reflection-peak separation of 2.72nm (334GHz) and a reflectivity of 99.9% are UV induced in buried waveguides by using a single amplitude modulated W-exposure through a phasemask.
