Investigations on focusing grating fabricated in polymer waveguides by electron beam lithography are reported. With blazed gratings, an incoupling efficiency of 42 per cent is achieved. A curvature correction of the grating lines allow the focusing properties to be improved: a spotsize which corresponds to one and a half times the diffraction limit is archieved.
