Revolutionizing Optoelectronics: Susumu Noda's Legacy and the 2026 Rank Prize
Discover the story of Susumu Noda, a pioneer in semiconductor lasers, whose breakthrough PCSEL technology earned him the prestigious 2026 Rank Prize for Optoelectronics.
Pioneering Breakthroughs in Laser Technology
In what has become a defining moment in the field of optoelectronics, Susumu Noda from Kyoto University has been awarded the 2026 Rank Prize. His development of the groundbreaking Photonic Crystal Surface Emitting Laser (PCSEL) has set new standards for semiconductor lasers and broadened their application scope, particularly in high-precision manufacturing and LIDAR technologies. Noda’s achievement has not only earned him personal recognition but also marked a significant leap in laser technology.
From Concept to Recognition: Journey of Innovation
Noda’s journey with PCSELs began in the late 1990s. These innovative lasers utilized photonic crystals to introduce a periodic dielectric constant that created a photonic band-gap. This advanced approach allowed PCsELs to produce high-quality, symmetric beams with narrow divergence, while boosting the overall brightness and functionality, maintaining the benefits of typical semiconductor lasers.

Overcoming Traditional Challenges
Unlike conventional semiconductor lasers that required external elements to enhance their performance, PCSELs have outperformed them by integrating high functionality, compactness, and high wallplug efficiency. As a result, they serve a wide range of applications, challenging fiber optics in various domains.
A Surprising Yet Deserved Recognition
Noda expressed his honor and surprise upon receiving the prestigious award, stating, “I am extremely happy to know that more than 25 years of research on photonic-crystal surface-emitting lasers has been recognized in this way.” His research continues to thrive, working towards its social implementation and further development.
Bridging the Past and Future in Optoelectronics
With a career that started with a BSc and PhD from Kyoto University, Noda’s work has consistently pushed the boundaries of what’s possible in electronics and beyond. His innovations have created paths for future research and development in optoelectronics, bridging the past’s foundational knowledge with futuristic applications.
The Rank Prize Significance
Established by Lord J Arthur Rank in 1972, the Rank Prize is awarded biennially, recognizing excellence in fields like nutrition and optoelectronics. With a cash award of £100,000, it celebrates groundbreaking contributions to these vital fields.
A Continuing Legacy
As the world looks forward to the formal award event in June 2026, Noda’s contributions emphasize the necessity of persistent research and innovation in technology. His perseverance and results not only enhance current technological capabilities but pave the way for future discoveries in the realm of optoelectronics.
