**8. Summary**

Nowadays white light based on blue laser diode has become the rapidly growing technology for high speed VLC and high CRI lighting. This Chapter aims to understand the blue laser diode-based VLC and SSL using color converter remote phosphor to overcome the bottlenecks of LED-based VLC and SSL. Recently, phosphors are using everywhere; therefore, multiple approaches and research have been carried out to find the best color conversion phosphor. We have studied the downconversion luminescence properties of cesium lead bromide quantum dot <sup>3</sup> (CsPbBr -QD) and Potassium silicon fluoride <sup>4</sup> K SiF : Mn 2 6 <sup>+</sup> (KSF). Furthermore, we have studied the properties of generated white light from commercially available phosphor coated on glass CL-827-R45-XT by changing bias currents. We demonstrated a VLC and SSL system simultaneously with a data rate of 1.6 Gbps over 50 cm free-space link based on NRZ-OOK modulation. Additionally, the generated white light exhibits with low CCT of 4435 K and CRI of 93.8. According to our discussions, we can conclude that laser diode based generated white light can be used for both high-speed visible light communication and solid-state lighting simultaneously.
