The research team led by Professor Yamamoto Hiji of the National Institute of Informatics of Japan has successfully developed a new "laser" that does not use light. The research team used the "excitation particles" that the electron holes competed with each other to replace the light waves, and the "laser" was excited by the action of the particles. The power required for the new "laser" is less than one percent of conventional lasers. This new type of "laser" can be used as a medium for information transfer in large-scale integrated circuits (LSIs), and the power consumption of large-scale integrated circuits using such "laser" media can be made small. The research was published in the British journal Nature.
"Excited particles" are produced and present in semiconductors, weigh only a thousandth of a hydrogen atom, and have the properties of waves. Yamamoto's research group irradiated the semiconductor with an electromagnetic wave with a wavelength of 800 nm, and found that it can be closely combined with the "excited particles" and the weight can be changed to less than one ten thousandth of the ordinary "excited particles". In a specially constructed semiconductor terminal, the research team resonated electromagnetic waves with "excited particles" to create a new "laser."
At present, electrons in metal wiring in a large-scale integrated circuit are responsible for signal transmission. In order to reduce power consumption, many countries are advancing research on the use of lasers instead of electrons for signal transmission. This time, the new "laser" developed by the National Institute of Informatics of Japan is a more advanced technology, exploring a new way for the signal transmission of integrated circuits, and is of great significance for the future energy saving of electronic equipment.
