Samenvatting

We present our latest results on the design and fabrication of mode-field conversion tapers for low-loss optical interconnects. These structures are fabricated by means of two-photon polymerization-based 3D nanoprinting. We experimentally demonstrate that our 3D nanoprinted downtapers outperform conventional lensed fibers for low-loss edge coupling of single-mode fibers with SOI, Si3N4 and InP-based photonic integrated circuits. They are also more robust as they allow butt coupling rather than free-space coupling. Non-linear taper profiles allow shortening the length of the downtapers while keeping their performance. We also demonstrate 3D nanoprinted uptapers that allow for relaxation of the lateral misalignment tolerances.
