Giant optical spin-orbit interactions in ferroelectric van der Waals waveguides
Ding Xu, Saeed Rahmanian Koshkaki, Vicente Galicia +14
Optical spin-orbit interactions (SOI) link photonic spin to momentum, offering a route toward on-chip polarization control and beam steering. Nevertheless, achieving sufficient opt…
On-demand steering of hyperbolic chiral polaritons
Andrea S. Dai, Fuyang Tay, Ding Xu +11
Control of light polarization and propagation in sub-wavelength architectures is foundational to nanophotonic technologies. A frontier direction is to leverage strong optical spin-…
Observation of Coherent Ferrons
Jeongheon Choe, Taketo Handa, Chun-Ying Huang +16
Excitation of ordered quantum phases gives rise to collective modes and quasiparticles, as exemplified by spin waves and magnons emerging from magnetic order. Extending this paradi…
Exciton Delocalization Suppresses Polariton Scattering
Yongseok Hong, Ding Xu, Milan Delor
Exciton-polaritons (EPs) are part-light part-matter quasiparticles that combine large exciton-mediated nonlinearities with long-range coherence, ideal for energy harvesting and non…
Spatiotemporal imaging of nonlinear optics in van der Waals waveguides
Ding Xu, Zhi Hao Peng, Chiara Trovatello +6
Van der Waals (vdW) semiconductors have emerged as promising platforms for efficient nonlinear optical conversion, including harmonic and entangled photon generation. Although majo…
