Full-wave nonlinear microscopy reveals guided channel for ultrafast polariton transport
Qingyi Zhou, Piper Fowler-Wright, Zongfu Yu +2
We show how finite-difference time-domain (FDTD) simulations can be extended to model ultrafast nonlinear microscopy, enabling the prediction of spatially-resolved pump--probe sign…
Quantum Nonlinearity for Optical Neural Computing
Qingyi Zhou, Jungmin Kim, Yutian Tao +4
The rapid scaling of deep neural networks comes at the cost of unsustainable power consumption. While optical neural networks offer an alternative, their capabilities remain constr…
Real-Space Imaging of Guided Exciton Polaritons in Free-standing Monolayer WSe2
Manuka Suriyage, Hao Qin, Xueqian Sun +5
Monolayers of transition metal dichalcogenides (TMDCs), known for their strong excitonic states with high binding energies in the visible spectrum at room temperature, offer great…
Avalanche Sensing via Kerr frequency comb in an Optical Microcavity
Chenchen Wang, Qingyi Zhou, Lan Yang +1
Sensors based on optical microcavities enhance light-matter interactions within an ultraconfined volume, enabling high-sensitivity detection across a wide range of sensing applicat…
DogWeave: High-Fidelity 3D Canine Reconstruction from a Single Image via Normal Fusion and Conditional Inpainting
Shufan Sun, Chenchen Wang, Zongfu Yu
Monocular 3D animal reconstruction is challenging due to complex articulation, self-occlusion, and fine-scale details such as fur. Existing methods often produce distorted geometry…
Efficient simulation framework for modeling collective emission in ensembles of inhomogeneous solid-state emitters
Qingyi Zhou, Wenxin Wu, Maryam Zahedian +2
An efficient simulation framework is proposed to model collective emission in disordered ensembles of quantum emitters. Using a cumulant expansion approach, the computational compl…
