Nick Holoniako is an ordinary researcher at General Electric in the United States. In 1962, he developed the world's first LED light emitting diodes that emit red light. He believed that obtaining red light would also make it possible to obtain light of other colors. In 1963, he wrote in Reader's Digest that the future of lighting and display will be dominated by light-emitting diodes!
In the second year after Holoniako invented the light-emitting diode, he left General Electric and became a professor of electrical engineering at the University of Illinois. He wants to cultivate more students through education, and use them to improve and promote the application of light-emitting diodes. Many physics PhDs he taught at the university became entrepreneurs, chief executives, or researchers. And after improving its invention, it successfully achieved the commercialization of light-emitting diodes.
In 1963, Holoniako invented the world's first semiconductor laser that emitted red light. This type of laser diode has now become a key component in CDs, DVDs, players, laser printers, and copiers. Since the 1970s, Holoniako has been working on extending the emission spectrum of light-emitting diodes to invisible light - infrared. The red emitting diode will not only change long-distance communication systems, but also the appearance of computers. Currently, at the age of nearly 80, Holoniako is still pursuing the dream of using light-emitting diodes to integrate a large number of optical switches on chips, thereby realizing the optical computer.
Holoniako's contribution lies in providing new inspiration to future generations, opening up new avenues for researching new light sources and devices. People have made light-emitting diodes that can produce different colors such as yellow, green, blue, and white. Nowadays, giant display screens made of light-emitting diodes are popular around the world, and the displayed numbers are very clear even during the day. Almost all traffic lights and indicator lights inside cars use light-emitting diodes.
