A compound parabolic concentrator includes a coupling surface for positioning on a sensitive surface of a photodetector of a receiving device, a collecting surface for receiving optical signals, and a side surface located between the coupling surface and the collecting surface, the side surface including two inclined and symmetrical parabolic portions when viewed in a cross-sectional plane passing through a reference axis of the compound parabolic concentrator, wherein the side surface is defined by an equation using input parameters including a dimension of the sensitive surface of the photodetector, an acceptance angle, a first refractive index of a medium in which the compound parabolic concentrator is to be immersed, a second refractive index of a material used to manufacture the compound parabolic concentrator, and a diametrical expansion factor.

Method for designing an expanded compound parabolic concentrator (ECPC) correctable for collecting light in the near-field

A lighting and communication system includes a first optical fiber portion, a second optical fiber portion, a third optical fiber portion, a fourth optical fiber portion and a fifth optical fiber portion that are distinct, wherein a visible light transmitter is positioned at a first end of the first optical fiber portion, a modulated light signal transmitter is positioned at a first end of the second optical fiber portion, a second end of the first optical fiber portion and a second end of the second optical fiber portion are connected to a first end of the third optical fiber portion, a modulated light signal receiver is positioned at a first end of the fourth optical fiber portion, a second end of the third optical fiber portion and a second end of the fourth optical fiber portion are connected to a first end of the fifth optical fiber portion.

Lighting and communication system comprising a transmitter and a receiver of modulated light signals

A system includes an optical fiber assembly, a receiver and a telescope, the receiver being positioned at a receiving end of the optical fiber assembly, the telescope being positioned at a collecting end, the receiver being arranged to receive uplink modulated light signals collected by the telescope and travelling through the optical fiber assembly, the telescope comprising an optical concentrator having an inlet face and an outlet face with a surface area smaller than that of the inlet face, the telescope further including a gradient-index lens dispose d coaxially with respect to the optical concentrator so that an inlet face of the gradient-index lens extends opposite the outlet face of the optical concentrator, the collecting end of the optical fiber assembly opening out opposite an outlet face of the gradient-index lens.
