摘要：

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