Mode Control and Dynamic Population Gratings in Quantum-Dot Lasers
Xiangpeng Ou, Artem Prokoshin, Hongyan Yu +5
Single-mode operation is essential for integrated semiconductor lasers, yet most solutions rely on regrowth, etched gratings, or other complex fabrication steps that limit scalabil…
Fostering cultural change in research through innovative knowledge sharing, evaluation, and community engagement strategies
Junsuk Rho, Jinn-Kong Sheu, Andrew Forbes +30
Bringing together researchers, funders, industry partners, and publishers from 14 countries across 5 continents, we advance the debate around open-science, assessment and learning.…
Electrically pumped quantum-dot lasers grown on 300 mm patterned Si photonic wafers
Chen Shang, Kaiyin Feng, Eamonn T. Hughes +9
Monolithic integration of quantum dot (QD) gain materials onto Si photonic platforms via direct epitaxial growth is a promising solution for on-chip light sources. Recent developme…
Turnkey locking of quantum-dot lasers directly grown on Si
Bozhang Dong, Yating Wan, Weng W. Chow +5
Ultra-low-noise laser sources are crucial for a variety of applications, including microwave synthesizers, optical gyroscopes, and the manipulation of quantum systems. Silicon phot…
Analysis of the spontaneous emission limited linewidth of an integrated III-V/SiN laser
Weng W. Chow, Yating Wan, John E. Bowers +1
This paper describes a calculation of the spontaneous emission limited linewidth of a semiconductor laser consisting of hybrid or heterogeneously integrated, silicon and III-V intr…
ENLighten: Lighten the Transformer, Enable Efficient Optical Acceleration
Hanqing Zhu, Zhican Zhou, Shupeng Ning +4
Photonic computing has emerged as a promising substrate for accelerating the dense linear-algebra operations at the heart of AI, yet adoption for large Transformer models remains i…
