A generalized approach to photon avalanche upconversion in luminescent nanocrystals
Artiom Skripka, Minji Lee, Xiao Qi +7
Photon avalanching nanoparticles (ANPs) exhibit extremely nonlinear upconverted emission valuable for sub-diffraction imaging, nanoscale sensing, and optical computing. Avalanching…
Indefinite and Bidirectional Near Infrared Nanocrystal Photoswitching
Changhwan Lee, Emma Z. Xu, Kevin W. C. Kwock +14
Materials whose luminescence can be switched by optical stimulation drive technologies ranging from superresolution imaging1-4, nanophotonics5, and optical data storage6-8, to targ…
4Dia: A tool for automated 4D microscope image alignment
Nimmy S. John, Michelle A. Urman, ChangHwan Lee
Recent advances in microscopy enable three-dimensional live imaging at a high resolution. Long-term live imaging of a multicellular organism requires immobilization of the organism…
Giant nonlinear optical responses from photon avalanching nanoparticles
Changhwan Lee, Emma Xu, Yawei Liu +10
Avalanche phenomena leverage steeply nonlinear dynamics to generate disproportionately high responses from small perturbations and are found in a multitude of events and materials,…
Broadband optical parametric amplification by two-dimensional semiconductors
Chiara Trovatello, Andrea Marini, Xinyi Xu +11
Optical parametric amplification is a second-order nonlinear process whereby an optical signal is amplified by a pump via the generation of an idler field. It is the key ingredient…
