    摘要: The invention relates to a fiber optic material which comprises a polymer and at least one organic compound introduced therein. Said organic compound is a condensed aromatic ring system having two or more aromatic rings that are isocyclic or heterocyclic, wherein every heteroatom is associated with exactly one ring if the ring is heterocyclic. The fiber optic material according to the invention is preferably used for the core of an optical waveguide.

    摘要: In a method for the manufacture, by means of lithography, of ceramic small and micro-parts, a pre-ceramic silicon containing polymer layer is deposited on a highly temperature resistant substrate and then dried at room temperature. The layer is then exposed in an image pattern to electromagnetic radiation and the exposed layer is developed in an organic solvent to remove the non-exposed areas. The preparation is then pyrolyzed at more than 900° C. and finally sintered at a temperature of at least 1600° C. to form a ceramic structured layer on the substrate.
