January 17, 2015: Nobel laureate Shuji Nakamura, co-inventor of the blue LED, has predicted that the future will be full of lasers. Adressing a press conference, he said laser diodes, which are already been used as car headlights, will gradually replace LEDs and will dominant the lighting industry. It will be used to power wireless communications networks as well.
Nakamura, a materials science professor at the University of California, Santa Barbara, pointed out that LEDs have a limitation. When the input power is increased, LEDs not only become very bright, but their efficiency starts decreasing. However, on the other hand, the input power for laser diodes increases continuously with very high efficiency, he said.
For this major differentiation, in the near future, all lighting will be from laser-based lighting,? he added.
Laser diodes can also be used for ?intelligent lighting? like smartphone-controlled projectors that display imagery or data on walls or floors, said Nakamura.
Laser diodes can also boost wireless communications. He said laser-based Li-Fi can also replace LED-based Li-Fi, as a laser diode-based version would be even fasted than LED-based Li-Fi. Li-Fi is an optical communications technology that uses light instead of radio waves to send data at 3.5Gbps or more speed.
?The modulation speed of laser lighting is much faster than LED lighting, almost 1,000 times faster, so the Internet speed would become much, much faster,? Nakamura said.
