Enhanced fluorescent antenna with a wide field of view using CsPbBr₃ colloidal quantum dots

Fluorescent antennas (FAs), integrated into the receivers of optical wireless communication (OWC) systems to absorb and convert incident optical signals, show great promise for future applications due to their wide field of view (FoV). In this paper, we fabricated a fluorescent antenna by doping poly(lauryl methacrylate) (PLMA) with cesium lead bromide (CsPbBr₃) perovskite quantum dots (QDs). We develop a novel approach that combines experimental measurements and Monte Carlo simulations to assess the antenna's communication performance comprehensively, with a particular focus on experimentally measuring and analyzing its wide FoV. The results demonstrate that in communication systems, the receiver with the FA can achieve a bandwidth of 27 MHz and a data rate of 110 Mbps at a bit error rate (BER) of 3.8 × 10^-3 based on modulation of on-off keying (OOK). Additionally, the proposed FA as a cubic concentrator extends the unilateral FoV of the receiver to at least ±70° and, under ideal conditions, enables nearly 360° full-view effective reception.
