Frequency Response of a Fluorescent Fibre Detector Intended for Visible Light Communications

White LEDs can be simultaneously used for communication and illumination. This paper describes the frequency response of an omnidirectional light collector (OLC) made from fluorescent plastic optical fibres able to filter the slow luminescence from the phosphor coating of the LED. This OLC is useful for omnidirectional detection of modulated optical carrier in the visible spectrum. The OLC is intending to relax the mobility constraints of an optical wireless receiver.
