Single-Shot Realization of 10000-Mode Octave-Spanning Artificial Gauge Fields
Lida Xu, Apurva Padhye, Supratik Sarkar +6
Artificial gauge fields (AGFs) enable photons and other bosons to emulate fermionic phenomena such as chiral edge transport and quantum Hall phases; however, existing theories and…
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…
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…
Near-Visible Topological Edge States in a Silicon Nitride Platform
David Sharp, Christopher Flower, Mahmoud Jalali Mehrabad +5
Demonstrations of topological photonics have so far largely been confined to infrared wavelengths where imaging technology and access to low-dimensional quantum materials are both…
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…
