Title: One Photon, Two Photons, Red Photon, Blue photon: Upconverters for Efficient Solar Harvesting and Biological Force Sensing
Location: 67-3111 Chemla Room
Jen's research develops new nano and optical materials for applications ranging from high-efficiency energy conversion and storage to bioimaging and manipulation. This research has led to demonstration of negative refraction at visible wavelengths, development of a subwavelength silicon electro-optic modulator, design of plasmonic optical tweezers for enantioselective sorting, demonstration of a metamaterial fluid, and synthesis of high-efficiency and active upconverting materials. Most recently, Jen has developed in situ techniques to visualize chemical transformations and light-matter interactions with nanometer-scale spatial resolution.
