Bandwidth limits of luminescent solar concentrators as detectors in free-space optical communication systems

摘要

a Graphic depicting the principle of operation of an LSC-VLC system. Data are transmitted by modulating a source of light, typically LEDs. Light may come from any direction and is collected by fluorescent collectors that concentrate it to a photodiode on their edge. The photodiode converts the optical signal into an electrical signal, which is then processed by the receiver circuits. b At their limits, LSCs can be represented by a simple RC circuit, where Vin is the input and represents the absorbed incident light
