Visible light communications (VLC) has the potentia
l to
play a major part in future smart home and next gen
communication networks. There is significant ongoin
g work to
increase the achievable data rates using VLC, to st
andardize it and
integrate it within existing network infrastructure
The future of VLC systems depends on the ability t
o fabricate low
cost transceiver components and to realize the prom
ise of high data
rates. This paper reports the design and fabricatio
n of integrated
transmitter and receiver components. The transmitte
r uses a two
dimensional individually addressable array of micro
light emitting
diodes (μLEDs) and the receiver uses an integrated
photodiode array
fabricated in a CMOS technology. A preliminary resu
lt of a MIMO
system implementation operating at a data rate of ~
1Gbps is
demonstrated. This paper also highlights the challe
nges in achieving
highly parallel data communication along with the p
bottlenecks in integrated approaches
