Abstract
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 2.72 nm (334 GHz) and a reflectivity of 99.9% are UV induced in buried waveguides by using a single amplitude modulated UV-exposure through a phasemask
