Mode spectroscopy is a widely used technique for characterising planar optical waveguides. 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 into a photo-curable polymer by copying master grating generated holographically. The grating couplers were applied to various waveguides.
