摘要： A high-index contrast waveguide component is presented, which is based on the fast changing of the transmission properties of an optical waveguide by applying electric voltages, or by embossing electric currents. The waveguide consists of a high-refractive waveguide core surrounded by a low-refractive surrounding material, which at least area by area has electro-optical properties. By applying a voltage to completely or partially optically transparent electrodes, an electric field is generated having a strong overlap with the optical mode, being in interaction with it, and therefore changing the transmission properties of the waveguide. The transparent electrodes or supply line areas are laminar, connected at low resistance with conductor paths of high conductivity by means of structures continually repeated along the propagation direction. Thus, it is possible for example to very fast load the capacity being effective between the electrodes, and to thus achieve a high electric band width. In certain embodiments, the waveguide core itself consists of one or more electrically conductive stripes being used as electrodes at the same time. These embodiments make especially small switching voltages possible.For example, the presented component makes fast electro-optical modulators with small switching voltages possible, which modulators may be integrated together with electronic components on a common semiconductor substrate (e.g. silicon).

摘要： In an integrated optical circuit, light from a light source is polarized and coupled to a first and second strip waveguide. A waveguide coupling element couples the two optical signals from the two strip waveguides to different polarization modes of an optical fiber line. The optical fiber line is connected to a measuring head, which reflects the optical signal and in which a phase difference between the two optical partial signals is modulated in a magnetic field. In the waveguide coupling element, the reflected signal is split into two optical partial signals having the same polarization and the phase difference between the two partial signals is determined. A phase modulator device provides for closed-loop operation. Compared to fiber-optical concepts, the number of splices is reduced.

摘要： A method for making optical connections with optical waveguides includes mounting the optical waveguides or a device comprising the optical waveguides, on a component carrier. A partial region of the optical waveguides is embedded in a volume of resist material. Positions of the optical waveguides to be connected are detected with reference to a coordinate system using a measuring system. Favorable, three-dimensional geometries are determined for optical waveguide structures for connecting the optical waveguides to each other at predetermined connecting locations and the optical waveguide structure geometries are converted to a machine-readable dataset. The optical waveguide geometries in the volume of the resist material are three-dimensionally structured using a direct-writing lithography device operating on the basis of the machine-readable dataset. The structured resist material is treated using physical or chemical methods to form at least one optical waveguide structure having ends connected to predetermined connecting locations of the optical waveguides.
