    • 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.

    • The invention has improved parameters when compared with prior art devices; pump power was decreased by four orders and amplification of signal was increased by two orders. The main features of the invention are following. The nonlinear optical waveguide (1) is made on the basis of layered MQW-type structure, where unidirectional distributively coupled waves (Ip, Is), e.g. coupled waves having orthogonal polarizations, interact. Wavelength of optical radiation is chosen close to wavelength of resonnance in said structure. Input/output elements (10, 11, 12), taking into account the asymmetry of cross section of the nonlinear optical waveguide, are mounted at the input and output of the nonlinear waveguide making up a compact nonlinear-optic module. A small electrical current is injected across said nonlinear optical waveguide through the electrodes (2, 3), so as to increase gain and decrease pump optical power in high degree. The device contains also Peltier element and temperature sensor which help to obtain low predetermined critical power of pump radiation necessary for large signal gain and to set up necessary operation mode. The method of mounting and construction of optical elements of the device is also claimed. The technological reserves can improve already achieved record parameters. Application as all-optical transistor, all-optical switch, logic element and devices based thereon.

It provides a very high speed of modulation of optical radiation. It also gets an opportunity of reading the information with higher density of record. The modulator on the basis of magneto-optical Faraday effect contains optically connected: optical element (10) made from magneto-optical material with means (3) creating a variable magnetic field in it, a nonlinear-optical waveguide (4) and a separator of waves (5) having orthogonal polarizations. The possibility for rejection of atmosphere fluctuation and jamming is provided. The nonlinear-optical waveguide (4) can be made on the basis of a MQW-type structure. Inuput/output elements, taking into account the asymmetry of cross section of the nonlinear-optical waveguide are mounted at its input and output, making up a compact nonlinear-optic module. A small electrical current is injected across said nonlinear-optical waveguide through electrical contacts (12) so as to increase gain in modulation and decrease pump optical power in a high degree.
