Experimental observation of energy-band Riemann surface
Dali Cheng, Heming Wang, Janet Zhong +3
Non-Hermiticity naturally arises in many physical systems that exchange energy with their environment. The presence of non-Hermiticity leads to many novel topological physics pheno…
Superluminal Correlations in Ensembles of Optical Phase Singularities
Tomer Bucher, Alexey Gorlach, Arthur Niedermayr +16
Phase singularities are universal features found across diverse wave systems. Their ensembles exhibit distance correlations governing exotic material phases. However, the full corr…
Programmable Optical Filters Based on Feed-Forward Photonic Meshes
Carson G. Valdez, Anne R. Kroo, Marek Vlk +4
We demonstrate an integrated photonic circuit based on feed forward photonic meshes that can be programmed and reconfigured to perform arbitrary spectral filter functions. We inves…
Nanophotonic thermal management in X-ray tubes
Simo Pajovic, Charles Roques-Carmes, Seou Choi +5
In X-ray tubes, more than 99% of the kilowatts of power supplied to generate X-rays via bremsstrahlung are lost in the form of heat generation in the anode. Therefore, thermal mana…
Creating high-dimensional topological physics using a single ring resonator
Dali Cheng, Heming Wang, Charles Roques-Carmes +2
In spaces of three or more dimensions, there exists topological physics of significant richness that has no lower-dimensional counterparts. To experimentally explore high-dimension…
Universal programmable and self-configuring optical filter
David A. B. Miller, Charles Roques-Carmes, Carson G. Valdez +4
We propose an approach to integrated optical spectral filtering that allows arbitrary programmability, can compensate automatically for imperfections in filter fabrication, allows…
