Abstract
Chlorophylls and carotenoids, key components of photosynthetic systems, are proposed for molecular communications at the nanoscale with the mechanism of resonance energy transfer. Both types of pigments are introduced focusing on their exceptional properties like energy harvesting, ultra-low energy consumption during transmissions, picoseconds delays, an ability for signal conversions, and bio-compatibility. The theoretical considerations are supported by two spectroscopic experiments on the photosystem II complex. The first experiment aims at the description of the photosystem II including calculation of the energy transfer efficiency between carotenoids and chlorophylls. In the second one, the photochemical efficiency is estimated, showing how effective the chlorophylls are in further energy processing. With the experimentally determined values, communication and energetic performance are analyzed, the probability of channel blockage is calculated and the energy consumption per bit is estimated. Treating carotenoid molecules as transmitters, chlorophylls as receivers, and the energy transfer between them as a way to encode information, a throughput up to 1 Gbit/s is achievable with a bit error rate below 10(-3), average transmission delays about 20 ps, and energy consumption c.a. 2.0 x 10(-18) J/bit. These results indicate a high potential of photosynthetic systems for nanocommunications and other related applications, due to suitable energetic characteristics in terms of energy harvesting abilities and low consumption for data transmissions.
