The 46th Honda Prize 2025 Awarded to Dr. Kenichi IGA
Pioneering contributions to the conception and advancement of Vertical-Cavity Surface-Emitting Laser (VCSEL), and management in its useful application
TOKYO, Japan, September 9, 2025 – (JCN Newswire)– The Honda Foundation (Founders: Soichiro and Benjiro Honda, President: Hiroto Ishida) has actually chosen to award the 2025 Honda Prize to Dr. Kenichi Iga (Honorary Professor at Institute of Science Tokyo and 18th President of previous Tokyo Institute of Technology), for his conception of Vertical-Cavity Surface-Emitting Laser (VCSEL) and pioneering contributions to its fundamental research study, and his management in its useful application. The VCSEL produces light vertically from the chip surface area and makes it possible for high-density range development * 1 and high-density combination.
* 1 A structure incorporating numerous laser aspects set up in a routine pattern. Allows high-density combination and synchronised multi-point irradiation.
Fixing the obstacles of semiconductor lasers
Semiconductor lasers are laser oscillators * 2 that run on source of power similar to those of basic electronic circuits, utilizing small aspects with sides determining less than 1mm. Today, they are utilized in a wide variety of fields in every day life and market, such as fiber optics interactions and checking out optical disks like DVDs. This innovation was considerably advanced towards useful application by Dr. Kenichi Iga, who proposed the surface-emitting laser as a kind of semiconductor laser. It has attributes not discovered in standard semiconductor lasers, such as steady oscillation at a single wavelength, ease of mass production, the capability to constantly differ wavelength, and low power usage.
Technological development through surface-emitting lasers
Compared to traditional semiconductor lasers which give off light horizontally relative to the substrate, VCSEL releases light vertically, making it more compact, and produces less disturbance amongst surrounding modes, making it possible for high density combination. Surface-emitting lasers are an important innovation in short-range LiDAR * 3, which specifically maps the state of a car’s environments (varying from 10s of centimeters to a number of meters).
High-density positioning allows synchronised multi-point emission over a broad location, permitting rapid scanning. Very little wavelength variation is essential to making it possible for high-precision measurement. Furthermore, the compact and thin type element helps with simple combination into bumpers, mirrors, and doors, and its low power intake is likewise thought about an outstanding quality for vehicle elements.
* 2 A gadget that constantly creates waves of a particular frequency, when waves produced from an amplifier are fed back to the amplifier (feedback).
* 3 Technology that determines range to and shape of a things by irradiating it with laser light and evaluating the shown light information.
Understanding useful application of surface-emitting lasers
Dr. Kenichi Iga, who originated the useful application of surface-emitting lasers, proposed the principle in 1977. In 1988, Dr. Fumio Koyama (presently Distinguished Professor/Professor Emeritus at the Institute of Integrated Research, Institute of Science Tokyo), a trainee of Dr. Iga, was successful in attaining continuous-wave operations at space temperature level, leading the way for useful execution. Ever since, scientists worldwide have actually participated in surface-emitting laser research study, with associated documents now going beyond 60,000 worldwide. Worldwide adoption and advancement efforts by many business have actually resulted in commercialization of the innovation, bringing substantial changes to individuals’s lives, allowing ultra-high-speed, high-capacity parallel interaction in information centers and LANs, energy cost savings, 3D facial acknowledgment in smart devices, and growth into LiDAR.
The Honda Prize award event is set up to be held at the Imperial Hotel Tokyo on November 17, 2025. In addition to the reward medal and diploma, the laureate will be granted an overall of 10 million yen.
