OSC Colloquium: Thomas Allison, "Ultrafast Imaging of Electron and Exciton Dynamics in 2D Materials" April 5, 2022 Thomas Allison In this talk, I will discuss both the optical science behind these recent breakthroughs in tr-ARPES and recent results from my lab regarding graphene and monolayer WS2, 2D materials being used now in optoelectronic devices. Direct visualization of momentum-space wave functions enables the study of light-matter interaction with an unprecedented level of detail, with new discoveries unseen in previous measurements.

OSC Colloquium: Gregory Forcherio, "Advancing Infrared Vision with New Materials" March 7, 2022 Gregory Forcherio Naval operations in visually-degraded environments requires new approaches to the design of infrared electro-optic imagers, with particular emphasis on economical materials and/or architectures that potentiate room temperature operation with access to alternative sensing modalities and/or embedded processing. This talk with overview disruptive efforts at Crane to (i) develop smarter optics (e.g., with dielectric metasurfaces), (ii) search for Si-compatible focal plane array (FPA) materials for uncooled mid-wave sensing (e.g., with doped CdO or SiGeSn), and (iii) build multi-physics modeling & simulation infrastructure for rapid virtual prototyping and assessment of their imaging performance. Opportunities for faculty and student engagement with the Naval Surface Warfare Center, Crane will be highlighted. Read more
