Nonlinear frequency conversion underpins important technologies such as telecommunications and quantum computation; however, weak nonlinearities and architectures that resist miniaturization currently limit devices’ efficiency and widespread adoption...

Self-healing–-the ability of a structured beam to reconstruct its transverse profile after partial obstruction–-has been demonstrated for diffraction-free beams, where the recovery distance varies continuously with obstruction size. Here, we investigate...

Detecting trace amounts of molecules–-from explosives to biomarkers–-requires sensitive sensors. The characteristic vibrational and rotational modes of many such molecules lie in the THz range and act as molecular fingerprints, enabling label-free...

Achieving precise control of light intensity in 3D volumes is highly in demand in many applications in optics. Various wavefront shaping techniques have been utilized to reconstruct a target amplitude profile within a 3D space. However, these techniques...

Skyrmions, topologically non-trivial localized spin structures, are fertile ground for exploring emergent phenomena in condensed matter physics and next-generation magnetic-memory technologies. Although magnetics and optics readily lend themselves to two...

Tunable semiconductor lasers are indispensable for applications ranging from spectroscopy to telecommunications, yet achieving continuous, mode-hop-free tuning across broad frequency ranges in a compact, robust device remains challenging. Here, we present...

Multiphoton interference and entanglement are fundamental to quantum information science, yet extending these effects to higher-dimensional systems remains challenging given the imperfections and complexity of scaling conventional linear-optical setups...
