摘要： The present invention provides an optical branching device and an optical communication system which are easy to connect with optical fibers. In the optical branching device, when light emitted from an optical fiber in a front stage is incident on an entrance port of a multicore optical fiber, the light propagates through a first core and then is distributed from the first core to four second cores by core-to-core crosstalk between the first and second cores. The light beams distributed to the four second cores propagate through the respective cores and are emitted to four optical waveguides optically coupled core-to-core thereto within a fan-out part at exit ports.

摘要： The present invention is related to a method of fabricating an optical signal processor capable of eliminating design change of lens optical systems and so on. The optical signal processor includes input and output optical waveguides, and further includes a first lens optical system, a spatial wavelength-dividing element, a second lens optical system, and a spatial optical modulator, respectively arranged on an optical path between the input and output optical waveguides. For fabricating the optical signal processor, one or more optical waveguides each having a mode field diameter such that a desired band width of the transmission characteristics of the whole optical signal processor with respect to the light beam are selected as the input and output optical waveguides. When one optical waveguide is selected, the selected optical waveguide is applied as a common optical waveguide corresponding to both input and output optical waveguides. On the other hand, when two optical waveguides are selected, one is applied to the input optical waveguide and the other is applied to the output optical waveguide.

摘要： According to the present invention, as a result of using a depressed or trench-assisted light-receiving waveguide in which the core is surrounded by a layer having a refractive index lower than that of a cladding as light-receiving means for receiving light outputted from a multi-core optical fiber, the layer of a low refractive index can inhibit the propagation of noise, etc. from the cladding to the core. Consequently, even in cases where the inter-core crosstalk is small, it is possible to accurately measure the inter-core crosstalk since components different from crosstalk-derived components in optical power are reduced.
