ABSTRACT:
Optical components made of inorganic crystals, e.g. lithium niobate, have the drawback that they cannot be integrated on a semiconductor substrate. In addition to linear optical characteristics, polymer plastics also have strong, non-linear characteristics. According to the invention, these plastics are integrated on a semiconductor substrate and serve as polarizers, modulators, optical switches, etc. Additionally, they require less space than prior art crystals.
