Tokyo Institute of Technology: Mr. Iga, Edison Medal Winner: Development of surface emitting laser
-Edison Medal to Professor Emeritus of Tokyo Institute of Technology-
2021/01/01
Kenichi Iga (80) of Tokyo Institute of Technology:
Received the Edison Medal of the “Electrical and Electronic Society” (about 420,000 members) headquartered in the United States.
A new title will be added to Mr. Iga, who is known as a world authority on optoelectronics.
Developed surface emitting laser:
The latest smartphones can be unlocked by simply holding it over your face.
developed the latest technology that leads to this face recognition function.
Reason for award:
He considered the concept of a surface-emitting laser and made a pioneering contribution to its development.
Conventional laser light:
It came out only in the horizontal direction with respect to the substrate surface of the semiconductor.
This surface emission laser:
Mr. Iga made it possible to emit light in the vertical direction by stacking reflectors on top and bottom.
With this idea, many small laser elements can be arranged on a flat surface.
Field of use:
PC mouse that does not use balls,
Large-capacity optical communication, etc.
It is said that its applications continue to expand significantly.
