摘要： An optical component has first and second planar lightwave circuits. The first and second planar lightwave circuits are aligned and jointed such that the position of an i-th optical waveguide (where i is an integer greater than or equal to 1 and less than or equal to n) of the first planar lightwave circuit and that of an i-th optical waveguide of the second planar lightwave circuit are matched on a joint interface. An angle formed by the i-th optical waveguide of the first planar lightwave circuit and a normal of the interface is configured to vary in accordance with a value of i within a range satisfying the Snell's law.

摘要： Conventionally, there has been a problem that a structure in which optical signals outputting from a substrate facet in a PLC are optically coupled to a different bulk type optical device is so complicated that its assembly is laborious. There also has been a problem that a structure in which an output facet of a PLC is polished with an angle results in an increase in coupling loss in free space optics. With a lens bonded to an angled facet of a PLC, an optical circuit of the present invention achieves an optical coupling, with low loss, to a bulk-type optical device or another PLC with a simple structure. Moreover, a lens part and an optical fiber part are respectively bonded to different core apertures exposed on a single angled facet. Thereby, optical signals can be inputted to and outputted from the PLC through the single facet.
摘要翻译：通常，存在从PLC中的基板面输出的光信号光学耦合到不同体积型光学装置的结构如此复杂的问题，使得其组装费力。也存在这样的问题，其中以角度抛光PLC的输出端面的结构导致自由空间光学器件中的耦合损耗的增加。通过将透镜粘合到PLC的倾斜面上，本发明的光电路以简单的结构实现了对于散装型光学器件或另一个PLC的光耦合，具有低损耗。此外，透镜部分和光纤部分分别结合到暴露在单个角度小平面上的不同的芯孔。因此，光信号可以通过单面输入到PLC并从PLC输出。

摘要： A planar lightwave circuit is provided which can be easily fabricated by an existing planar-lightwave-circuit fabrication process, which can lower the propagation loss of signal light and which can convert inputted signal light so as to derive desired signal light. A planar lightwave circuit having a core and a clad which are formed on a substrate, has input optical waveguide(s) (111) which inputs signal light, mode coupling part (112) for coupling a fundamental mode of the inputted signal light to a higher-order mode and/or a radiation mode, or mode re-coupling part (113) for re-coupling the higher-order mode and/or the radiation mode to the fundamental mode, and output optical waveguide(s) (114) which outputs signal light. The mode coupling part or the mode re-coupling part is an optical waveguide which has core width and/or height varied continuously.

摘要： In a conventional optical signal processing device, a confocal optical system is configured in which a focusing lens is positioned at a substantially-intermediate point of a free space optical path. Thus, the free space optical system had a long length. It has been difficult to reduce the size of the entire device. The optical signal processing device of the present invention uses a lens layout configuration different from the confocal optical system to thereby significantly reduce the length of the system. The optical signal processing device consists of the first focusing lens positioned in the close vicinity of a signal processing device, and the second focusing lens positioned in the vicinity of a dispersing element. A distance between the dispersing element and the signal processing device is approximately a focal length of the first focusing lens. Compared with the conventional technique, the length of the optical path can be halved.
