Beyond LaserLight there is DataLight: LiFi for Mobility

KSLD Laser has been supplying high performance lighting solutions for automotive since 2019. More recently we have developed and marketed the Dual Emission SMD. It contains two solid state lasers, in most cases a GaN blue laser and an IR laser chip, plus a YAG phosphor. The two chips can be activated individually to produce white light and IR Light.
The brightness of the white source in the SMD is 3-5 times higher than that of any LED, which makes it ideal for long distance projection purposes. At the same time, it can generate LiFi data rates, which are 10-50 higher than those of LEDs. Such data rates equally apply for the IR source.

This combination of functions in one 7x7mm component makes the Dual Emission SMD an ideal proposition for Mobility applications, such as Aerospace and Automotive.
In the presentation the operation of the Dual Emission SMD will be explained and more specifically practical examples of LiFi applications in Mobility will be addressed.

View of the Speaker

Question 1: What drives you?
Being at the front of innovations in lighting and related technologies, as well as their applications in the market.

Question 2: Why should the delegate attend your session?
Laser-based LiFi is 10-50x faster than LED-LiFi. KSLD’s “Datalight” is embedded in a single Dual Emission SMD, which next to LiFi, also generates high brightness white light and IR light. The application field is broad, a.o. Mobility

Question 3: What emerging technologies / trends do you see as having the greatest potential in the short and long run?
I foresee a strong potential for LiDAR at short term and for LiFi enhanced LiDAR at mid term.
A recent market study shows that compared to other market segments Automotive is going to demand the highest data rates. The actual RF spectrum (WiFi / 5G and plus) will be saturated in a few years.

Question 4: What kind of impact do you expect them to have?
The combination of LiDAR and LiFi technologies is essential for bringing Autonomous Driving (AD) to full Level 3 and beyond, because of the need for high speed, large bandwidth data communication.

Question 5: What are the barriers that might stand in the way?
Automotive is actually switching to a full adoption of LEDs for front- and rear-lighting. The installed base of LED’s may turn out to be a barrier for the introduction of solid state laser based LiFi, i.e. at short term (3-5 years).

About John Peek
After graduation from Eindhoven University of Technology in 1977, I have taken many positions at Philips (Lighting). In 2015 I retired from the CTO position at Philips Automotive Lighting.
As an R&D professional, working and living in diverse cultures (European countries, the Americas, East Asia), I familiarized with the broad variety of innovation aspects, which – in interdependency – determine whether a new product/service proposition actually makes it in the marketplace.
After my retirement in 2015 I have joined the start-up (K)SLD Laser as a consultant to support them in growing the company and her business.

About KSLD Laser
SLD Laser was founded in 2013 by Prof. Shuji Nakamura (Nobel Laureate Physics 2014), Prof. Steve DenBaars, Dr. James Raring and Dr. Paul Rudy. The company operates facilities in Goleta-Santa Barbara, CA and in Fremont, CA. Her core competence is the development and production of GaN solid state lasers, based on the highly efficient semipolar laser diode technology. In January 2021 SLD Laser was acquired by Kyocera Japan, then adopting the name KSLD Laser.
The first industrial application is a high brightness, directional light source a.o. for automotive lighting. It has been in production and supplied to OEM’s since 2019.
Since then, the technology has evolved to include – next to lighting – distance measurement/sensing, LiDAR, Night Vision and LiFi.
