All-optical switching of nonlinear structured light in crystal-engineered van der Waals materials
Paolo Valisa, Marc Richstaetter, Bianca Sanfilippo +9
The orbital angular momentum (OAM) of light is a discrete, unbounded degree of freedom that underpins mode-multiplexed communications and high-dimensional quantum photonics. Yet, d…
Purcell enhancement of photogalvanic currents in a van der Waals plasmonic self-cavity
Xinyu Li, Jesse Hagelstein, Gunda Kipp +23
Cavities provide a means to manipulate the optical and electronic responses of quantum materials by selectively enhancing light-matter interaction at specific frequencies and momen…
Quasi-phase-matched up- and down-conversion in periodically poled layered semiconductors
Chiara Trovatello, Carino Ferrante, Birui Yang +15
Nonlinear optics lies at the heart of classical and quantum light generation. The invention of periodic poling revolutionized nonlinear optics and its commercial applications by en…
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…
