摘要： An optical wireless communication system for a vehicle comprises a photonic device and control electronics configured to control the photonic device. The photonic device comprises a plurality of photonic components arranged in a two-dimensional matrix array, and the control electronics are configured to control individually or in groups the photonic components of the plurality of photonic components. Each photonic component or each group of photonic components is configured, where appropriate conjointly with an optic, so as to emit and/or receive at least one optical wireless communication signal in a propagation direction that is discriminable relatively to a propagation direction of optical wireless communication signals emitted and/or received, respectively, by at least one other photonic component or by at least one other group of photonic components of the plurality of photonic components.

摘要： Provided is a beam-steering mechanism, comprising a lens and a light source positioned in a focal plane of the lens. One of the light source and the lens moves relative to the other of the light source and the lens. The light source outputs a light beam at the lens which forms an illumination spot on a surface from the light beam. The illumination spot moves in a direction in response to a movement of one of the light source and the lens.

摘要： The present disclosure provides a visible light communication transmitter, a visible light communication receiver, a visible light communication system, and a method of visible light communication, which are suitable for colour shift keying (CSK), as well as providing a method of CSK. The transmitter comprises at least six graphene-based light emitting devices of different peak transmission wavelengths from each other. The receiver comprises a corresponding number of graphene-based photodetectors of different peak reception wavelengths from each other. A system according to the disclosure comprises such a transmitter and such a receiver, wherein each respective one of the different peak reception wavelengths of the six graphene-based photodetectors corresponds to a respective one of the different peak transmission wavelengths of the graphene-based light emitting devices. Such a system allows a method of visible light communication with a colour constellation of at least six base colours.

摘要： A power over fiber system includes: a first data communication device including a power sourcing equipment device; a second data communication device including a photoelectric-conversion-and-optical-communication unit including a powered device; and an optical fiber cable. The first data communication device is capable of controlling low power supply and high power supply of the power sourcing equipment device. Feed electric power by the high power supply exceeds that by the low power supply. The first data communication device enables the high power supply after starting the low power supply to the second data communication device and receiving, therefrom, a signal indicating that the photoelectric-conversion-and-optical-communication unit has started. The photoelectric-conversion-and-optical-communication unit starts and transmits the signal to the first data communication device when receiving the low power supply, and enables extension of a range of a target that receives electric power from the powered device when receiving the high power supply.
