 Friday, August 11th at 1:00pm in Henley Hall Semiconductor nanostructures with low dimensionality like quantum dots are one the best attractive solutions for achieving high performance photonic devices. When one or more spatial dimensions of the nanocrystal approach the de Broglie wavelength, nanoscale size effects create a spatial quantization of carriers. When directly grown on silicon, they even show a four-wave mixing efficiency much superior compared to the conventional quantum well devices. This remarkable result paves the way for achieving high-efficiency frequency comb generation from a photonic chip. Quantum dot lasers are a good candidate for applications in optical routing and optical atomic clock and quantum information processing. This lecture will review the recent findings and prospects on nanostructure based light emitters made with quantum-dot technology and their applications.
Frédéric Grillot is currently a Full Professor at Télécom Paris (France) and a Research Professor at the University of New-Mexico (USA). His research interests include, but are not limited to, advanced quantum confined devices using III-V compound semiconductors, quantum dots quantum dashes, light-emitters based on intersubband transitions, non-classical light, nonlinear dynamics and optical chaos in semiconductor lasers systems as well as microwave and silicon photonics applications.
Professor Grillot has made outstanding technical contributions in photonics and optical communications. He has intensively contributed to the development of quantum dot devices enabling their utilization as future active devices with superior performance. In particular, his recent achievements on epitaxial quantum dot lasers on silicon are crucial for the development of isolation-free integrated technologies. Among his major achievements, he also reported the first private optical communication using mid-infrared chaotic light, giant pulses emission in quantum cascade devices as well as multigigabits operation in the thermal atmospheric window with unipolar quantum optoelectronics. Overall, his research is a strong input to the advancement of science and to the emerging practical applications in computer and quantum technologies, as well as in more traditional areas such as optical communications. Professor Grillot strongly contributes to promote and support the development of the general optics community. He has served diligently and successfully Optica in particular as an Associate Editor of Optics Express, now as a Deputy Editor since September 2022. As of now, he has published more than 130 journal articles, 3 book chapters, and delivered many invited talks in major international conferences and workshops. Frédéric Grillot is also a Fellow Member of the SPIE as well as a Senior Member of Optica and the IEEE Photonics Society. In 2022, he received the IEEE Photonics Society Distinguished Lecturer Award which honors excellent speakers who have made technical, industrial or entrepreneurial contributions to the field of photonics. |
