Summary:
Visible light communications (VLC) has potential to play a major part in the future smart home and future generation communication networks. There had been significant improvements in VLC technology in the last decade and a multi-Gigabit data rate is possible using light emitting diodes (LEDs). The commercial success of VLC systems, however, depends on the ability to fabricate low cost transceiver components and to realize the promise of high data rates. This talk focus on a new approach to establish the device parameters for integrated VLC system design by taking account of particular characteristics of the emitter and a receiver technology and combining them with power requirement for a particular modulation scheme. Different approaches including multiple inputs multiple outputs (MIMO), spatial modulation and ganging schemes to achieve high data rates will be discussed. The talk also highlights challenges in achieving highly parallel data communication along with the possible bottlenecks in integrated approaches will also be discussed. A new approach of generating a large bandwidth (in excess of 200 MHz) white light using a blue LED and super-yellow color converter will be highlighted.
