Towards high-precision manufacturing of 3D optical components using UV-curable hybrid polymers (Invited Paper)
Paper 9368-14

Hybrid polymers having already been applied in photonic applications as microlenses or 2D and 3D waveguides are promising candidates to manufacture optical systems down to the chip level. In this contribution, we report on the evaluation of hybrid polymer materials for two-photon absorption (TPA) lithography. Developed by micro resist technology GmbH with support from Fraunhofer ISC, the hybrid polymers are used in an innovative production method for directly manufacture individual 3D photonic structures impossible to generate with conventional 2D techniques. Teaming up as material and equipment supplier, we highlight the current launch of a collaboration targeting a closed technological ecosystem.

Two-photon polymerization of hybrid polymers for applications in micro-optics
Paper 9353-19
Author(s): Sönke Steenhusen, Fraunhofer-Institut für Silicatforschung (Germany); Frank Burmeister, Hans-Christoph Eckstein, Fraunhofer-Institut für Angewandte Optik und Feinmechanik (Germany); Ruth Houbertz, Fraunhofer-Institut für Silicatforschung (Germany), Multiphoton Optics GmbH (Germany)
Miniaturization and higher integration of opto-electronic components require highly sophisticated optical designs. This creates the demand for freeform technologies such as Two-Photon Polymerization (2PP) and new specially adapted materials like hybrid polymers (ORMOCER®s). Recent progress in the fabrication of micro-optical structures using 2PP and specially designed hybrid polymers (ORMOCER®s) is presented. Among the structures are freeform and aberration-optimized micro-lenses and multilevel diffractive optical elements. These components are discussed with respect to the fabrication process and their resulting optical performance. Furthermore, 2PP-initiated refractive index modification, offering high potential for energy-efficient fabrication of 3D optical interconnects, is discussed.
