Abstract
Investigations on focusing grating couplers fabricated in polymer wave guides 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 lim it is achieved.
