PureLiFi is a visible light communication technology (Li-Fi) based on LED light source chip technology, which indicates that lasers will better serve Li-Fi, and has developed laser-based "optical antennas", successfully taking the first step in this direction, and its modules can be used to embed mobile devices such as smartphone phones.
Ten years ago, Edinburgh-based pureLiFi was co-founded by Professor Harald Haas, the father of Li-Fi. It has been a leader in the development of Wi-Fi-like data and Internet transmissions. Li-Fi uses modulated light waves instead of Wi-Fi's radio waves. Its proponents have long praised it as safer than Wi-Fi because it doesn't cause electromagnetic interference and can alleviate the crowded Wi-Fi spectrum. But Li-Fi has yet to be widely adopted, in large part because computer and phone manufacturers don't embed Li-Fi chips like Wi-Fi, allowing Li-Fi users to plug in USB sticks or "dongles."
In recent years, visible light communication technology has been continuously developed and innovated, so that the LED light source chip is transferred to the laser chip. The modulation speed of the laser chip can be about 100 times faster, and at the same time, the light it can emit can travel about 100 times the distance of the LED. Such a move, compared to Wi-Fi, could help Li-Fi truly achieve "higher speed" favoritism in the market. Laser chips are likely to become "jet engine" boosters for the visible light communications industry.
Recently, Professor Haas, co-founder and chief scientific officer of pureLiFi, has surfaced as a consultant to Laser Backbone Kyocera SLD, a company that is helping the aviation industry develop laser Li-Fi systems.
In April, pureLiFi released the Light Antenna Module, which actually uses an infrared laser chip. The module is designed small enough to be installed in smartphones and is available to device manufacturers. pureLiFi also positions its laser components inside access points (usually luminaires) that send and receive data to these devices.
In April of the same year, pureLiFi posted a video on its official website showing two Moto G smartphones exchanging video files with each other over Li-Fi. The modified phone no longer uses an embedded Li-Fi chip. In contrast, pureLiFi is equipped with a laser Li-Fi circuit that connects directly to a phone without using a USB port. ”
For now, the cost of universally implementing laser Li-Fi equipment is still very expensive, but Professor Haas believes that industrial mass production can eventually reduce the cost of laser Li-Fi equipment and promote the widespread application of visible light communication technology. According to reliable sources, BMW has designed laser headlights into his 8 Series models. Huachuang Core Optical believes that this is just a good start for the popularization of visible light communication laser chips.
