Nonlocal metasurfaces enable quantum phase-gradient imaging
—
in Optics
What the study found The study found that a compact quantum phase-gradient imaging system can use two metasurfaces to both generate and analyze quantum light for phase imaging. The system combined a lithium niobate (LiNbO3) metasurface, used to generate spatially entangled photon pairs, with a silicon (Si) metasurface, used to extract phase gradients. Why the…
