    Abstract: The invention is directed to a method for fabricating an optical waveguide (100). Basically, it relies on setting on the lower cladding(11), both the waveguide cores (26L-48l) and light-reflecting features (23 -23c), e.g. mirrors or fiducial markers. The reflecting features and the waveguide cores constitute a core layer having an open structure. An upper cladding polymer (31) is then applied, which embeds the light-reflecting features and the waveguides. Thus, the upper cladding applied fills the space left vacant by the open structures. The components of the core layer are accordingly set in place during the fabrication process, before filling the cladding at the level at which they are located. Since the light reflecting features and waveguide cores can be set with high accuracy on the lower cladding (before applying the upper cladding), the problems of reworking (e.g. dicing) or refining position of a light-reflecting feature inserted a posteriori is circumvented. Advantageously, both the waveguide cores and reflecting feature scan be patterned onto the lower cladding. The reflecting features may further be obtained from a selective metallization process.

    Abstract translation: 本发明涉及一种制造光波导（100）的方法。 基本上，它依赖于在下包层（11）上设置波导芯（26L-481）和光反射特征（23-33c）两者。 镜子或基准标记。 反射特征和波导芯构成具有开放结构的芯层。 然后施加上包层聚合物（31），其嵌入光反射特征和波导。 因此，施加的上部包层填充由开放结构空出的空间。 因此，在制造过程中，在将包层置于其所处的水平面之前，将芯层的部件设置在适当位置。 由于可以在下部包层（在施加上部包层之前）以高精度设置光反射特征和波导芯，所以避免了插入后验的光反射特征的返工（例如切割）或精细位置的问题。 有利地，波导芯和反射特征扫描都被图案化到下包层上。 反射特征可以进一步从选择性金属化处理获得。

    Abstract: Aligning optical components with optical waveguides according to a common optical axis is done by an optical component assembly OCA, an adapter ADP and a waveguide assembly WGA. The OCA has optical components and a first alignment structure of a cavity (SC, figure 1) which is associated with the substrate of the OCA. The ADP presents a base surface BS with a first step structure S1. The WGA has a second alignment structure comprising a distinct step structure S3 designed according to the position of the waveguides within the waveguides assembly. The OCA, WGA and the ADP are positioned so that a sidewall of the cavity and the distinct step structure S3 are in contact with a sidewall of the first step structure SI. A second step structure S2 may also be provided.

    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.
