"Integrated mode locked lasers: Photonic integrated signal processing strategies to push the repetition rate limits" Prof. Guillermo Carpintero (Universidad Carlos III de Madrid, Madrid, Spain) Abstract Photonic integration technology platforms have enabled designers to develop their own laser structures, including semiconductor mode locked lasers with user defined repetition rates. In this talk we will analyze the physical limits imposed by the technology, and the methods to overcome this limits using on-chip photonic signal processing. Biodata Guillermo Carpintero is Professor at the Electronics Technology Department of Carlos III University of Madrid (UC3M). His main research line is photonic integrated circuits with application to the field of integrated microwave photonics, developing photonics-based systems for the generation of millimeter and Terahertz waves aiming at ultra-broadband (>10 Gb/s) wireless communication systems. He spent a sabbatical leave as Visiting Professor at University College London in 2011 with Prof. Alwyn Seeds and was a Research Fellow at Osaka University, Japan, in 2014 with Prof. Tadao Nagatsuma. Currently is coordinating an FET-Open project TERAmeasure developing novel instrumentation for the Terahertz range using hybrid integration of InP Photonic Integrated Circuits and High-speed photodiodes. |

"From Optical Communications to the Brain: Integrated 3D Silicon Photonics" Joyce Poon Abstract Foundry-manufactured, monolithically integrated multilayer silicon nitride-on-silicon photonic platforms are suitable for large-scale photonic circuits. These photonic platforms contain several waveguide layers, and light is routed amongst the layers to create 3D photonic devices and circuits. We have realized a suite of devices in these platforms, including ultra-low-loss waveguide crossings, multi-layer grating couplers, and efficient modulators. These advancements, which were initially driven by telecommunications, are leading to neurophotonic implants for brain activity mapping. No Other Talks! |

"Next-generation organic electro-optic materials for hybrid device architectures" Abstract Next-generation silicon-organic hybrid (SOH) and plasmonic-organic hybrid (POH) device architectures have led to renewed interest in organic electro-optic (OEO) materials for chip-scale photonic integration under a different set of design constraints than for bulk devices. State-of-the art hybrid devices are capable of 10x the electro-optic activity of LiNbO3 and far superior device footprints, power efficiency, and signal quality to competing device architectures. Fully realizing the multiple order of magnitude reduction in modulator size from advances in hybrid devices will require development of materials with exceptional electro-optic activity and refractive indices that have been optimized for these device architectures. Multiscale modeling, combining classical condensed-phase simulations and electronic structure theory, has provided many crucial observations that suggest how to design the next generation of OEO molecules. We apply a variety of computational techniques to identify bottlenecks to materials performance and develop routes for transformative improvement in electro-optic materials, in addition to leveraging insights in dendritic chromophore systems to improve thermal stability. Our calculations have already identified synthetically feasible materials predicted to yield > 2x performance improvements versus the state of the art and provide a pathway to order-of-magnitude improvement.
