In this chapter, we review our recent work on blue laser diode-based visible light communication and solid-state lighting. Gallium nitride (GaN) phosphor-converted white light-emitting diodes (Pc-WLEDs) are emerging as an indispensable solid-state lighting (SSL) source for next-generation display system and the lighting industry. Together with the function of lighting, visible light communication (VLC) using Pc-WLEDs has gained increasing attention to fulfill the growing demand for wireless data communication. Practically, the low modulation response and low emitting intensity of light-emitting diodes (LED) are the drawbacks for the development of ultrahigh-speed VLC and high-quality SSL system. Blue GaN laser diode (LD) and remote phosphor-based white light can be used for both high-speed VLC and SSL simultaneously. We demonstrated a color-rendering index (CRI) of 93.8, a correlated color temperature (CCT) of 4435 K, and a data rate of 1.6 Gbps under NRZ-OOK modulation by an exciting blue laser diode on narrowband green−/red-emitting composite phosphor film. This work opens up exciting possibilities for future high-speed indoor VLC and high-quality SSL.

We show fast LiFi information correspondence of more than 20 Gbit/s utilizing noticeable light from a laser-based white light radiating surface mount gadget (SMD) item stage that offers 10-100X the brilliance of regular LED sources. Furnished with high force blue laser diodes that proposal over 3.5 GHz of 3 dB transmission capacity, the laser-based white light SMD modules showed a sign to-clamor proportion (SNR) over 15 dB up to 1 GHz. The high SNR was joined with high request quadrature adequacy tweak (QAM) and symmetrical recurrence division multiplexing (OFDM) to amplify the transfer speed effectiveness. In this work, we present a laser based white light SMD module arranged with a solitary 3W blue laser diode mounted on heat-sink, optically coupled to a collimating optic, accomplishing a LiFi information pace of up 10Gbit/s. Moreover, we show frequency division multiplexing (WDM), from a white light SMD module designed with two blue laser diodes isolated in top frequency to fill in as discrete correspondence channels.
