We were honored to host the Thorlabs Mobile Photonics Lab on their inaugural cross-country tour from Newton, NJ to San Francisco, CA. The Mobile Lab provided students with the opportunity to experience hands-on photonics demos including biomedical optics and imaging, spectroscopy, and optical communications.  On October 6th, students, professors, research staff, and industry professionals gathered at Goleta Beach Area D to catch up, talk about photonics, and make new connections while enjoying excellent food catered by SB Chicken Ranch. There was good conversation with industry members from Thorlabs Crystalline Solutions, Nexus Photonics, Freedom Photonics, Quintessent, HPE, Praevium, and Kyocera SLD. Newer students got a chance to interact with current grad students and network with industry representatives. The event was a great success, with over 100 attendees.   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.

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. 
Friday July 21st, 1:00pm in Henley Hall 1010 In recent years, the monolithic integration of III/V-semiconductor materials and heterostructures on CMOS-compatible (001) Si-substrate is gaining increasing interest for the realization of novel integrated circuits with improved electronic, optoelectronic or photonic functionalities. The principal challenges of the III/V-material integration on CMOS-compatible (001) Si-substrates will be reviewed and possible solutions for the high-quality deposition of III/V-layer stacks will be demonstrated for large area 300 mm (001) Si-wafers by applying low-temperature metal organic vapour phase epitaxy (MOVPE) processes. Examples of successfully developed technologies including defect-free GaP-on-Si-template wafers as well as novel lattice-matched Ga(NAsP)-based laser stacks for Si-photonics applications will be presented and discussed.
Wolfgang Stolz is full professor and co-head of the Structure and Technology Research Laboratory (Material Sciences Center and Faculty of Physics, Philipps-University Marburg (Germany)), Adjunct Professor at the Optical Sciences Center (University of Arizona, Tucson (USA)) and Chief Technology Officer (CTO NAsP III/V GmbH, Marburg (Germany)). His current fields of activities include the epitaxial growth for a wide range of III/V-compound semiconductor material systems and heterostructures by applying metal organic vapour phase epitaxy (MOVPE) as well as realization of novel device concepts for electronic, solar cell and laser applications in particular also monolithically integrated on CMOS-compatible (001) Si-substrates.
