    Abstract: PURPOSE: An optical channel switch for a WDM(Wavelength Division Multiplex) transmission equipment and a control method therefor are provided to increase the flexibility of the operation and structure of a network by adding a switch function to an OADM(Optical Add/Drop Multiplexer) used in the WDM transmission equipment. CONSTITUTION: An optical waveguide combines an input port(411) and an output port(413) with a drop port(412) and an add port(414). A plurality of conductive members(421,422) are allocated on the optical waveguide to be opposite each other. A power supply unit(424) connects each conductive member(421,422) to its each electrode terminal and forms an electric potential difference. A switch element(423) selectively connects and disconnects a power supply path between the power supply unit(424) and the conductive members(421,422).

    Abstract: An optical delay generator comprises a first waveguide made from electro-optically active material resonantly coupled to a second non-electro-optically active waveguide. The first waveguide contains a chirped distributed Bragg reflector structure which reflects optical signals at a specific wavelength at a specific reflection point within the structure. An electric field applied to the first waveguide changes the refractive index of the electro-optically activematerial and thus shifts the reflection point. Optical signals reflecting from the reflection points are resonantly coupled into the second waveguide, and are thus not affected by the electric field applied to the first waveguide. The controllable optical delay applied to the optical signals results from control over the reflection point and the round-trip travel time for an optical signal forward propagating in the first waveguide, being reflected at the reflection point, and backward propagating in the second waveguide.

    Abstract: A preferred embodiment method of the invention uses a periodic optical structure, such as grating (12), on top of an optical waveguide structure (14). The optical structure is exposed ot an incident laser radiation with wavelength in one of the transition bands. Modulation of the incident laser radiation is controlled by the change in refractive index or absorption in the optical guided wave structure produced by the modulation voltage. A preferred method for designing a suitable periodic optical structure having broad pass bands with narrow transition bands uses a high coupling coefficient between the priodic structure and the optical waveguide mode. Increasing the product of the coupling coefficient and the length of the grating narrows the transition region band and increases sensitivity of the modulation.

    Abstract: The invention relates to a tuneable optical grid-assisted add-drop filter in codirectional mode of operation, which has the structure of a directional coupler filter with at least two adjacent wave guides having different refraction indices. The inventive filter must exhibit a spectral bandwidth of the filter transmission curve in the range from 50 GHz to 400 GHz for a high resolution in order to be tuneable and it must be producible in a more straightforward and more cost-effective manner, with dimensional tolerances higher than that of InP based add-drop filters. For that purpose, the material of the two wave guides is composed of two different classes of materials having different optical parameters. The thermal refraction index coefficient dn/dT, the electrooptical coefficient dn/dE or the dispersion dn/d lambda of these two materials differentiate from each other in such a way that, in case of an action carried out upon the two wave guides with the same technical means in a view to changing the temperature, the electric field or the wavelength, effects with different strength occur and therefore, means for changing these parameters are provided. A polymer and silica are used as wave guide materials arranged vertically or horizontally relatively to each other. For changing the optical parameter dn/dT, a device for modifying the temperature is used to influence the whole surface of a chip which contains the filter, said device being possibly identical to a device for stabilising the chip temperature.

    Abstract: A diffraction grating for a waveguide or for externally incident light. The grating includes a substrate and an electrooptic structure extending over it. The electrooptic structure may include a waveguide having a propagation axis. A first and a second electrode structure are provided on either side of the electrooptic structure so that an electric field is generated in the electrooptic structure when a potential is applied to the electrodes. The first electrode structure has an interdigitated configuration defining a plurality of fingers. In use, respective potentials V0 and V0 + DELTA V are applied to adjacent fingers. The diffraction grating induced in the electrooptic structure by the periodic electric field advantageously has a refractive index adjustable by varying V0 and DELTA V and a spatial periodicity adjustable by varying DELTA V.

    Abstract: In an optical micromechanical process for changing the phase of guided waves for the purpose of modulating phase or intensity, and/or for switching guided optical waves between various outlets, and/or for deflecting optical waves, and/or for changing the resonance frequencies of frequency filters and resonators, and a measurement process for measuring very small mechanical displacements and/or mechanical forces or pressures, including the pressure of sound waves and ultrasonic waves, and/or accelerations, the distance d between a section (1') of an optical wave guide (1) in an integrated optic or fibre optic circuit and a phase-shifting element (5) separated from said section (1') by an intermediate space (4) is varied by forces (6) or by thermal expansion due to changes in temperature. The phase of the guided wave (3) is thereby modulated, and reciprocally the changes in the distance d and hence small mechanical displacements and the forces (6) which produce them are determined from the measured phase changes.
