This paper presents a novel fluorescent receiver for Visible Light Communications that combines a broad field-of-view with a significant gain, and simultaneously enables wavelength-division-multiplexing for data communications. These characteristics are achieved by creating a receiver that includes a stack of two fluorescent optical antennas, each designed to receive a different part of the spectrum and create two separable communication channels. The device outperforms the theoretical étendue limit in terms of the combination of field-of-view and gain it can achieve. Furthermore, the demonstrated de-multiplexing of blue and green spectral components enables the parallel streaming of data by wavelength division
