In recent work, we combined conventional top-down fabrication methods with bottom-up techniques (surface chemistry and self-assembly methods) to develop on-chip optical devices that incorporate NLO optical small molecules and optically-triggerable molecules. These hybrid systems provide access to optical behavior and performance not attainable with conventional material systems. In this seminar, I will discuss a couple examples of NLO small molecule integrated resonators, including Raman lasers and all optically-switchable devices.​

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.
