Manipulatable Cascade Pumping Single-Photon Upconversion

|
By Qi Xiao, Wen Xu, Xiumei Yin, Na Zhou, Xinyao Dong, Ge Zhu, Xixian Luo, Yinglin Song, Bin Dong
| Nature Verified
Abstract Photon upconversion (UC), while promising for infrared photonics, is fundamentally constrained by limited spectral response range, low efficiency, and slow response speeds. Here, we present a machine learning-guided single-photon UC strategy based on cascade pumping that implements a “LEGO-inspired photon stacking” mechanism, in which intermediate state of lanthanide ions (Ln3+) becomes a “virtual ground state” for direct single-photon pumping to target energy levels.
