Frédéric Grillot, Jianan Duan, et al., on ACS Photonics cover

equipe GTO vignette
Frédéric Grillot and Jianan Duan participated in writing an invited paper recently published in ACS Photonics in collaboration with UC Santa Barbara, Stanford University, Intel Corp. and Sandia National Labs. This work has been recommended by the journal’s board for the cover of the September issue.

Frédéric Grillot is Professor at Télécom Paris, France and at the University of New Mexico, USA. He was also a Visiting Professor at the University of California Los Angeles (UCLA) where he taught laser dynamics and quantum mechanics. His current research focuses on photonics and quantum technologies for optical communications.

Jianan Duan received the Ph.D. degree in Optoelectronics from University of Paris-Saclay, France, in 2019. From 2019 to 2020, he was the Post-Doctoral Researcher with Télécom Paris, Institut Polytechnique de Paris, France. Since 2021, he has been an Assistant Professor at Harbin Institute of Technology, Shenzhen, China. His current research interests include advanced semiconductor laser, silicon photonics and laser dynamics.

Epitaxially grown InAs quantum dot laser devices have shown great advantages over their quantum well counterparts. High-performance FP lasers, DFB lasers, mode-locked lasers, photodetectors, tunable lasers, and micro-ring lasers have been realized with such material systems. Robust operation at 80°C has been achieved for devices epitaxially grown on a CMOS-compatible Si substrate, signifying the potential of utilizing such devices as the on-chip light sources in the photonic integrated circuit.
