  A Silicon Photomultiplier, SiPM, is a metasystem of Avalanche Photodiodes,
APDs, which embedded in a specific purpose electronic, becomes a metadevice
with unique and useful advanced functionalities to capture, transmit and
analyze information with increased efficiency and security. The SiPM is a very
small state of the art photo-detector with very high efficiency and
sensitivity, with good response to controlled light pulses in the presence of
background light without saturation. New results profit of such metadevice to
propose a new receiver-emitter system useful for Visible Light Communication,
VLC.
