Nick Holoniako is an ordinary researcher at General Electric Company in the United States. In 1962, he developed the world's first red-emitting diodes (LED-light-emitting diodes). He believes that if you can get red light, it will be possible to get other colors of light. In 1963, he wrote in the US "Reader's Digest" that in the future, the field of lighting and display will be the world of light-emitting diodes!
The second year after Holoniaco invented the light-emitting diode, he left General Electric to become a professor of electrical engineering at the University of Illinois. He wants to train more students through education and use them to improve and promote the application of light-emitting diodes. Many of his PhDs in physics taught at the university became entrepreneurs, chief administrative officers or researchers. And its invention has been improved to successfully realize the marketization of light-emitting diodes.
In 1963, Holoniaco invented the world's first red-emitting semiconductor laser. This laser diode has now become a key component of CDs, DVDs, players, laser printers and copiers. From the 1970s onwards, Holonjako began to extend the light-emitting diode light spectrum to invisible light --- infrared light. The infrared-emitting diode will not only change the long-distance communication system, but also the face of the computer. Nowadays, Holoniako, who is nearly 80 years old, is still pursuing it, intending to use the light-emitting diode method to integrate a large number of optical switches on the chip to realize the dream of an optical computer.
Holoniaco's contribution is to give new inspiration to future generations, and open up new ways to study new light sources and new devices. People have made light-emitting diodes with different colors such as yellow, green, blue and white. Nowadays, giant display screens made of light-emitting diodes are used all over the world, and the numbers displayed are very clear even during the day. Almost all the traffic lights and all the indicators in the car use light-emitting diodes.
