    Abstract: An optical device comprises a substrate having a plane surface. An optical path is disposed on the substrate and extends in a plane parallel to the surface of the substrate. A recess intercepts the optical path. An optical element is provided for modifying light incident thereon. The optical element is moveable within the recess between a first position in which the optical element is located in the path and a second position in which optical element is remote from the path. A cantilever suspends the optical elements for movement within the recess between the second and first positions in a direction normal to the surface of the substrate.

    Abstract: The essential feature is the step of generating a controllable 'dynamic' intensity field profile with a controllable beating pattern in a multimode superposition of different modes, as e.g., a fundamental mode and a higher order mode as e,g., the TEO mode and T E1 mode of an input wavelength entering the input site of an AWG apparatus, whereby said beating pattern is controlled in a fixed, or in variable, predetermined way, as e.g., with a fixed or a wavelength dependent power ratio and beating pattern, for improving the mode overlap in a receiver waveguide associated with an output site of said apparatus. With variable conditions, a lower number of converter units is required. In a 8:1 multiplexer, for example, there is needed just one converter unit at its output. A 1:8 demultiplexer can be obtained by solely reversing the AWG apparatus.

    Abstract: A singlemode lightwaveguide-coupling element is positioned between an initial waveguide section which there has a basic final width (W0f) and a final waveguide section which there has a basic initial width (Wn+1i) which is bigger than the basic final width (W0f). The lightwave directions of both waveguide sections are inclined at a predetermined total angle (DELTAalpha) towards each other. Starting from the initial waveguide section, the lightwaveguide element comprises intermediate waveguide sections each of which at its end has a lightwave direction which is inclined towards the lightwave direction at its opposite end at an inclination angle (DELTAalphav), such that the sum of all inclination angles equals the predetermined total angle (DELTAalpha).

    Abstract: The invention concerns AlGalnP/GalnP visible laser diodes and LEDs withimproved maximum output power. This is achieved by embedding the active region of the diode (30), e.g. a GalnP active layer (35), between very thin pand n-doped AlGalnP barrier layers (34.1, 34.2) and thick p- and n-doped AlGaAs cladding layers (33, 36). The inventive barrier layers (34.1, 34.2) are employedto avoid tunneling and spill over of carriers from the active region (35) into the cladding (33, 36). These barrier layers (34.1, 34.2) can be very thin thus allowing bandgap engineering and providing for barriers with low defect density. In addition the low resistance of the AlGaAs cladding reduces the thermal and electrical resistances of the device.

    Abstract: The invention relates to a method for creating a pattern on a substrate comprising a first alignment structure, using an elastomeric stamp comprising a patterning structure and a second alignment structure. The method comprises a moving step for moving the elastomeric stamp towards the substrate, and a deformation step for deforming the patterning structure with a tensile or compressive force generated by cooperation of the first alignment structure and the second alignment structure.
