摘要：

Mode spectroscopy is a widely used technique for characterising planar optical waveguides. Prism couplers are mostly used due to their versatility. For higher-index waveguides like SiO2/SiN or GaInAsP/InP, prism coupling is hampered by the lack of suitable high-index material for fabricating coupling prisms. In this case, short-period grating couplers could be used, instead. We describe the fabrication of "exchangeable" grating couplers with 1200, 1800, and 2400 lines/mm into a photo-curable polymer by copying master grating generated holographically. The grating couplers were applied to glass and Si/SiO2/SiN waveguides, and results were compared with those obtained using prism coupling. Fabrication of gratings with shorter periods is under way.
