The "Best Paper Award" is conferred to research papers accepted at OECC/PSC2025 that demonstrate particularly outstanding achievements. This award recognizes the research presentation titled "High-Power Continuous Operation of a 1.3 μm-band InP-based Photonic Crystal Laser with an In-Plane Hetero structure," conducted in collaboration with Kyoto University. This work was acknowledged for its efforts toward the application of photonic-crystal surface-emitting lasers (PCSELs) which are gaining attention as a new type of laser, in optical communication.

Comment from Makoto Ogasawara, Optical Devices Department, Transmission Devices Laboratory, Sumitomo Electric
PCSELs are expected to have a wide range of applications, including data center communications, free-space communications, and sensing. We will continue to improve the characteristics of PCSELs and advance research aimed at their practical implementation in society.

* All co-authors are to receive the award.
