Abstract: There is provided a light emitting element and an optical waveguide that propagates light from the light emitting element. For example, the optical waveguide is an optical fiber or a silicon optical waveguide. The light propagating through the optical waveguide is light having components of a fundamental mode and a first order mode, and the light propagates through the optical waveguide while having a light intensity distribution in which high intensity portions alternately appear in one direction and another direction opposite to the one direction with respect to the center of a core along the optical waveguide. A light intensity distribution at an output end surface of the optical waveguide is a light intensity distribution corresponding to an intermediate position between a first position where the high intensity portion is in the one direction and a second position where the high intensity portion is in the another direction.

Abstract: 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.

Incident light incident upon the movable member from the optical component is, in the first state, attenuated and emitted to an outside such that power of the light is lower than power of the light when the movable member is held in the second state.

Abstract: To relax the accuracy with respect to a deviation with respect to an optical axis or an angular deviation, and thus to reduce costs. An optical waveguide is included that performs propagation only in a reference mode at a first wavelength. 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 light entering the optical waveguide deviates with respect to an optical axis or deviates angularly, propagation is performed in at least the first order mode in addition to the reference mode, the first order mode being generated due to the deviation with respect to the optical axis or the angular deviation. 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 deviation with respect to an optical axis or an angular deviation, and thus to reduce costs.

A data block containing capability information indicating existence/non-existence of compatibility with an extended function is received from the external device through the transmission channel. A layer field that indicates the connection layer is provided in this data block. A check is made to determine whether all the devices existing in the path are compatible with the extended function based on the value of the layer field provided in the data block, and the contents of the transmission signal are then determined.

Abstract: 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.
