We present the design, fabrication and characterization of a broadband lossless matching layer for shallow lens arrays. The matching layer we propose is based on silicon pyramids fabricated on top of the lens array by means of laser ablation. This matching layer has the advantage that it covers over an octave of bandwidth. We have compared the performance of this matching layer with the commonly used parylene-C matching layer at the center of the targetted band, 500 GHz. The matching layer based on the silicon pyramids has 1.6 dB higher transmission.
