Multi-timescale frequency-phase matching for high-yield nonlinear photonics
Mahmoud Jalali Mehrabad, Lida Xu, Gregory Moille +9
Integrated nonlinear photonic technologies, even with state-of-the-art fabrication with only a few nanometer geometry variations, face significant challenges in achieving wafer-sca…
Data Shift of Object Detection in Autonomous Driving
Lida Xu
With the widespread adoption of machine learning technologies in autonomous driving systems, their role in addressing complex environmental perception challenges has become increas…
Quantum Metamorphosis: Programmable Emergence and the Breakdown of Bulk-Edge Dichotomy in Multiscale Systems
Mahmoud Jalali Mehrabad, Alireza Parhizkar, Lida Xu +6
Multiscale synergy -- the interplay of a system's distinct characteristic length, time, and energy scales -- is becoming a unifying thread across many contemporary branches of scie…
Observation of topological frequency combs
Christopher J. Flower, Mahmoud Jalali Mehrabad, Lida Xu +8
On-chip generation of optical frequency combs using nonlinear ring resonators has opened the route to numerous novel applications of combs that were otherwise limited to mode-locke…
On-chip multi-timescale spatiotemporal optical synchronization
Lida Xu, Mahmoud Jalali Mehrabad, Christopher J. Flower +7
Mode-locking mechanisms are key resources in nonlinear optical phenomena, such as micro-ring solitonic states, and have transformed metrology, precision spectroscopy, and optical c…
An exponent tunable network model for reproducing density driven superlinear relation
Yuhao Qin, Liang Gao, Lida Xu +1
Previous works have shown the universality of allometric scalings under density and total value at city level, but our understanding about the size effects of regions on them is st…
