We report on the latest advances in printing 3D complex optical systems. We report inclusion of the color black into printing materials, as well as printing without additional alignment onto both sides of a substrate.
We examine the influences of strain and stess onto the polarization state of light after propagation. We also present our ansatz to include shrinkage into the systems design.
We report on applications in quantum technology, in particular on coupling quantum emission into single mode fibers, on optical trapping, and on multimode imaging in micro endoscopy. We also report on the smallest wide-angle endoscope in the world, which gives aberration corrected images for a viewing angle of 120°.
