Optical materials and componentsThe Fraunhofer Institute for Silicate Research ISC


Micro-optical components such as lenses, gratings, photonic crystals, and diffractive optical elements employed in optoelectronic devices and by the optical industry are increasingly required to operate in environments that demand very good ageing stability. There is also a need to reduce manufacturing costs and limit the consumption of materials, both in mass production and the fabrication of highly specialized components. Compared with pure polymer materials, inorganic-organic hybrid polymers exhibit outstanding optical characteristics. Moreover, they can be relatively easily modified to suit diverse requirements thanks to their chemical structure and wide range of processing options. Among the many possible structuring techniques, nano-imprint lithography and two-photon absorption polymerization are particularly suitable as a means of implementing complex, three-dimensional features. Furthermore, these materials are compatible with standard production processes in the microelectronics and semiconductor industries.
