Abstract:
Anordnung zur Umlenkung der Lichtausbreitung in Lichtwellen leitenden Strukturen beruhend auf dem Prinzip der Prismenkopplung, wodurch eine Lichtwelle aus einem ersten Lichtwellenleiter (1) durch einen Koppelspalt (2) in einen Kopplungskörper (3) und von dort durch einen zweiten Koppelspalt (4) in einem zweiten Lichtwellenleiter (5) umgelenkt wird.
Abstract:
The invention relates to an optical system for opto-optical information processing, which can be used in the field of integrated optics, especially for light-controlled switching, branching light and regenerating optical signals in communications networks. The aim of the invention is to provide a means of processing optical signals simply and flexibly. The inventive optical system uses a waveguide array in which the individual waveguides are coupled evanescently. At least one signal beam of a known wavelength is coupled into the waveguide array at an angle which prevents the signal beam from being diffracted when passing through said waveguide array, with at least one control beam of a known wavelength. The signal beam and the control beam cross inside the waveguide array, so an influence can be exerted.
Abstract:
The invention relates to a device for deflecting light propagation in optical wave guide structures, based on the principle of prism coupling. A light wave from a first optical wave guide is deflected into a coupling body by means of a coupling slit and is then deflected into a second optical wave guide by means of a second coupling slit.
