Abstract

Planar hyperbolical lenses with an average efficiency of 85% for coupling a 40 μm wide beam into a 4 μm wide waveguide are realised. The total length required for the beam compression is 600 μm, with a lateral index contrast of 0.01. Good agreement is found between the BPM predicted and the measured lens efficiencies.
