摘要： The invention features a programmable optical chip. The optical chip has a plurality of optical functions, each of which is connected to a waveguide having a core and a cladding. A photosensitive layer is disposed between at least three of the waveguides, and the photosensitive layer has a refractive index similar to that of the cladding prior to exposure to irradiation. The photosensitive layer changes refractive index upon exposure to irradiation to selectively form an optical connection between at least two of the waveguides.

摘要： To provide a hydraulic master cylinder with inlet ports and outlet ports arranged in an angle to each other wherein the outlet ports can be on either side of the housing without the need of two different casts, the master cylinder according to the invention is equipped with either two sets of protrusions adapted to be machined into inlet ports or two sets of protrusions adapted to be machined into outlet ports. The two sets of identical protrusions are arranged symmetrically with respect to the one set of different protrusions. Thus, depending on the desired side of the outlet ports, only one set of the two sets of identical protrusions is machined while the other set remains an unmachined accumulation of material.
摘要翻译：为了提供具有彼此成角度配置的入口和出口的液压主缸，其中出口可以在壳体的任一侧上，而不需要两个不同的铸件，根据本发明的主缸装备有两组突起，适于被加工成入口端口或两组突出部，适于加工成出口。两组相同的突起相对于一组不同的突起对称地布置。因此，取决于出口的期望侧，仅加工两组相同的突起的一组，而另一组仍然是未加工的材料堆积。

摘要： An optical mode transformer. The optical mode transformer features a low index core, a high index core having a first tapered region, with the high index core embedded within the low index core and with the low index core serving as a cladding for a waveguide defined by the high index core embedded in the low index core, and a cladding layer surrounding the low index core, with the cladding layer including one or more materials with different refractive indices than those of the low index core and high index core.
