Talks by MPO

DLW: High Speed Printing: Joint Session with Conferences 11271 and 11292

Fabian Hilbert: Impact of massive parallelization on two-photon absorption micro- and nanofabrication
February 4, Time: 11:50 AM – 12:10 PM

The use of polymerization via two-photon absorption (TPA), also known as High-Precision 3D Printing, is gaining increasing attraction. Since TPA is a scanning technology, industrial throughput fabrication can be achieved either by intelligent fabrication strategies and an excellent material basis, but also by multi-spot exposure strategies. Massive parallelization is demonstrated, which was realized by beam splitting diffractive optical elements (DOE). Simultaneous fabrication with more than 100 focal spots will be reported. With this approach, micro- and nanostructures are fabricated and application possibilities for metaoptics will be illustrated. Important aspects like scan speed and laser power will be addressed.

See Fabian in action at Photonics West 2019.


Benedikt Stender: Industrial use of high precision 3D printing (Invited Paper)
February 4, Time: 2:00 PM – 2:30 PM

Industrial use of High-Precision 3D Printing via two-photon absorption (TPA) requires high structure homogeneity at a reproducible level. Although still mainly used in academia, the interest for industrial application is continuously increasing. For this purpose, a novel fabrication strategy for scalable fabrication will be presented. Additionally, reproducibility in structure formation will be analyzed for selected elements with respect to overall size, angle generation and lens characteristics. The results demonstrate both scalable processes and high reproducibility provided by a stable process during fabrication.


Components and Packaging for Laser Systems VI

Willi Mantei: Compact packaging of multi-wavelength gas sensors up to the MWIR
February 4, Time: 11:40 AM – 12:00 PM

Semiconductor laser dies are nowadays commonly applied for the detection of gases. Although the benefit of semiconductor laser dies is their small size, the final sensor module’s footprint is significantly enlarged by bulky optical elements. To significantly reduce cost and to simplify the sensor module fabrication, a process is proposed based on High Precision 3D Printing which supplies homogeneous beam profiles by directly fabricate a cylindrical microlens on the laser die’s facet. Lifetime measurements reveal high performance beyond 7,500 hrs. This approach was extended to MIR laser dies and to combiners which enable multi-wavelength selectivity, and thus reduce the number of components and the footprint of
sensor units.



Join Conference 11286: Optical Interconnects XX,
Session 5: Novel Optical Waveguide and Integrated Interconnect Technologies, chaired by Ruth Houbertz, CEO and Managing Director of Multiphoton Optics.
The session will be held on February 5, 2020, from 8:20 am to 10:10 am, in Room 215 (Level 2 South)


Looking forward to seeing you in San Francisco, California! Come and see us at our booth and experience our Direct Laser Writing equipment in Augmented Reality!

Sincerely yours,



The metalens is part of a project that has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 780278.
