Bottom-Up meets Top-Down - A Novel Approach towards 3-D Optical Devices

摘要

Building materials from the bottom-up is complementary to conventional top-down materials processing. Inorganic-organic hybrid polymers designed for optical applications, were synthesized by hydrolysis/ polycondensation reactions, resulting in storage-stable resins built-up by nm-size organically functionalized primary particles (oligomers). The organically functional groups are typically oligo-(meth)acryl or styryl which allows one to pattern the resin by two-photon polymerization (2PP) processes using femtosecond lasers. With this method, any arbitrary structure can be directly written in three dimensions into the hybrid polymer with a resolution down to approx. 100 nm. The materials and the patterning process will be discussed with respect to applications in photonic devices.
