Polarization vector conjugation in a photonic integrated circuit
Anna J. Miller, Carson G. Valdez, Anne R. Kroo +5
We show how to perform polarization conjugation of light in a simple apparatus without any nonlinear optical materials, based on self-configuring Mach-Zehnder interferometers fed b…
Vacuum Fluctuation-Induced State Switching in Degenerate Optical Parametric Oscillators
Yihao Huang, Seou Choi, Rom Simovitch +5
Bistable driven-dissipative systems near bifurcations can exhibit noise-activated switching between steady states. Here, we investigate how quantum vacuum fluctuations induce such…
Neural network inverse design of nanophotonic scintillators
Nathan Regev, Avner Shultzman, Francis Loignon-Houle +2
Scintillators are materials converting high-energy radiation into optical light, essential in a range of technologies such as medical imaging systems and security scanners. Scintil…
Dosimetric characterization of a nanophotonic scintillator and applications to real-time in-vivo total body irradiation dosimetry
W. Jeffrey Zabel, Dixin Chen, Louis Martin-Monier +7
Purpose: Recent advances in metasurface photonics and manufacturing have enabled a nanophotonic surface coating to be applied to conventional scintillators, which has been shown to…
Diffractive cascades for polychromatic hard X-ray focusing
William Michaels, Simo Pajovic, Joshua Chen +2
Diffractive focusing of hard X-rays has traditionally required structures with large aspect ratios due to the limited interaction of most materials with X-rays. This has increased…
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…
