“L.E.D. has already contributed a lot to the energy consumptions. It is a large surprise for us,” Nakamura said.
Nakamura has devoted himself to research in the development of Gallium Nitride (GaN), thin film technology and Blue L.E.D. technology for more than 20 years. However, he and his team are not content with the status quo. His focus point has transferred from L.E.D. lighting to laser lighting. According to Nakamura, laser lighting is a huge lighting technology and he and his team recently made a significant technological breakthrough in this area.
Laser lighting is the same size as CHIF (Chanel Interface), but its current density is 1000 times higher than blue L.E.D. lighting. This means that by using tiny CHIF of laser lighting, we can make much brighter light.
“I love doing research because research is just like solving mysterious puzzles. Every time we did the experiment and got some data, I love to think and analyze about [this] data and how did [this] data come out,” Nakamura said. “Even though sometimes I was stuck on some problems for quite a long time, I still love the feeling of solving problems and solved it out in the end. I had to develop many products when I worked for the Japanese company, but it is still normal for people to take three to four years to invent something and [make] it to products.”
He expresses great concern and confidence toward the youth and research.
"I am still ambitious and willing to do research with young students, and I love to recruit young students; young students are always very creative and bright. Even I obeyed the order as a student, but I was still very creative at [a] young age,” Nakamura said. “The students are young, that is the most important thing. Basically, students proposed a lot ideas and advices during the research. They enjoy the research and freedom, and also they are very smart. They can do what they want and get the patent.”
“Basically, it is now study time for young students, like reading papers and doing [research]. After studying a lot, you should try to challenge new [things], which means the research. But the new challenge means also you have to pick a new path, which means many people go in this way, then you have go to the totally different way alone and take the risk,” he said. “You need to study a lot and fast because knowledge is the base of your research. Without knowledge you cannot do anything, and if you want to earn yourself a reputation, you need to take the risk.”
