摘要： To mitigate the accuracy of misalignment to reduce costs, and to suppress an inter-mode propagation delay difference to enable high-quality transmission of signals. An optical waveguide is configured to propagate only a fundamental mode at a first wavelength and propagate at least a first-order mode as well as the fundamental mode at a second wavelength. The optical waveguide is configured such that a refractive index distribution of a core and a cladding is controlled so that the inter-mode propagation delay difference is within a predetermined threshold, for example, the inter-mode propagation delay difference is zero, when communication is performed using light of the second wavelength. For example, the first wavelength is in a 1310-nm band and the second wavelength is in an 850-nm band.

摘要： To relax the accuracy with respect to a positional deviation, and thus to reduce costs.
An optical waveguide and a light path adjuster are included, the optical waveguide performing propagation only in a reference mode at a first wavelength, the light path adjuster adjusting a light path such that input light is guided to a core of the optical waveguide. Communication is performed using light of a second wavelength that enables the optical waveguide to perform propagation in at least a first order mode in addition to the reference mode. When there is a positional deviation, input light that is not headed for the core of the optical waveguide is guided to the core due to the light path adjuster adjusting a path of the light. This results in a reduction in a loss of coupling of optical power. Further, propagation is performed by the optical waveguide in at least the first order mode in addition to the reference mode, the at least the first order mode being generated due to the light path adjuster adjusting a path of the input light. This results in a reduction in a loss of coupling of optical power. This makes it possible to relax the accuracy with respect to a positional deviation, and thus to reduce costs.-

摘要： To properly measure the bending amount of an optical waveguide routed in an electronic device or the like. An optical signal outputted with a second wavelength from the optical waveguide is received by a light receiving unit. In this case, the optical waveguide allows propagation only in a basic mode at a first wavelength and the second wavelength is a wavelength where the optical waveguide allows propagation at least in a primary mode in addition to a basic mode. The bending amount of the optical waveguide is obtained by a processing unit on the basis of the amount of a primary mode component included in the optical signal with the second wavelength. For example, the processing unit obtains the bending amount of the optical waveguide by using the ratio of the amount of the primary mode component included in the optical signal with the second wavelength and the amount of the basic mode component included in the optical signal with the second wavelength.

摘要： The coupling loss of optical power on a reception side due to an axis deviation on a transmission side is satisfactorily mitigated. A connector body including an optical path adjusting unit and a lens is provided. The optical path adjusting unit adjusts an optical path such that the diameter of incident light is reduced while the incident angle is kept. The lens collects light whose optical path has been adjusted, and causes the light to be incident on a light receiver. For example, light incident on the optical path adjusting unit is collimated light. Furthermore, for example, the optical path adjusting unit has a through hole in a central portion. While the incident angle of light to the light receiver satisfies an NA, the focal distance of the lens is decreased. This can mitigate the coupling loss of optical power on a reception side due to an axis deviation on a transmission side.
