Comparative Test of Novel Fluorescent Optical Antennas for LED‐ and Laser‐Based Optical Wireless Communications

Advanced Optical Materials, EarlyView.
New fluorescent optical antennas are realized and tested for diverse Optical Wireless Communication (OWC) applications. The fluorescent concentrator slabs, based on different organic fluorophores, convert and convey the digital data conveyed through intensity modulation of incoming light toward a small‐area photodiode.

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

Advanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...
