Nanophotonic control of spatial information in scintillation detectors
Joshua Chen, Simo Pajovic, Seou Choi +9
X-rays enable non-invasive imaging across medicine, security, materials science, and beyond, yet modern systems remain constrained by the need to resolve finer structures at lower…
Three-dimensional confinement of light in photonic crystals without bandgaps
Manxi Shi, Sachin Vaidya, Ali Ghorashi +2
We demonstrate that confinement of light in three dimensions is possible in photonic crystals without a complete photonic bandgap. Our approach exploits symmetry-protected quadrati…
Supercollimating photonic crystal scintillators
Seou Choi, Sachin Vaidya, Charles Roques-Carmes +1
Scintillators convert X-ray energy into visible or near-visible photons, enabling applications in high-energy particle detection and X-ray imaging. Increasing scintillator thicknes…
Tunable Nanophotonic Devices and Cavities based on a Two-Dimensional Magnet
Ahmet Kemal Demir, Luca Nessi, Sachin Vaidya +3
Central to the field of nanophotonics is the ability to engineer the flow of light through nanoscale structures. These structures often have permanent working spectral ranges and o…
Large-scale self-assembled nanophotonic scintillators for X-ray imaging
Louis Martin-Monier, Simo Pajovic, Muluneh G. Abebe +9
Scintillators are essential for converting X-ray energy into visible light in imaging technologies. Their widespread application in imaging technologies has been enabled by scalabl…
Non-reciprocal frequency conversion in a multimode nonlinear system
Sahil Pontula, Sachin Vaidya, Charles Roques-Carmes +3
Nonlinear optics has become the workhorse for countless applications in classical and quantum optics, from optical bistability to single photon pair generation. However, the intrin…
