About
Kimio Sumaru is a leading researcher in organic photonics and optoelectronic materials, with a particular focus on photochromic compounds and their applications in spatial light modulation. His most cited work introduces a groundbreaking optically-addressed spatial light modulator (OASLM) fabricated using a diarylethene derivative, a type of organic photochromic thin film. Sumaru’s key contribution lies in demonstrating a fabrication method that involves heating and pressing a dye-dispersed polymer between glass plates in a vacuum, resulting in a device with exceptional durability and stable data retention. This innovation enables effective coloration and bleaching under visible light irradiation, addressing critical limitations of earlier organic modulators. Although his most cited paper has garnered 3 citations, its impact is notable for pioneering stable, high-performance organic photonic devices that bridge materials science and optical engineering. Sumaru’s work is essential for researchers exploring non-volatile optical memory, real-time holography, and adaptive optics, offering a practical pathway toward robust, low-cost spatial light modulators. His research continues to influence the development of organic photochromic materials for next-generation display and data storage technologies.
