Advancing nonlinear nanophotonics: harnessing membrane metasurfaces for third-harmonic generation and imaging
-
Abstract
Dielectric metasurfaces are crucial for enhancing optical nonlinear generation, particularly membrane metasurfaces with multipolar resonances and compact size. Investigating silicon dimer-hole membrane metasurfaces, Rahmani, and Xu show how bound states in the continuum (BICs) can be formed and transformed into quasi-BICs by adjusting hole gaps. This innovation enables efficient conversion of infrared images to visible range, promising applications in nonlinear photonics and near-infrared imaging technologies. -

THG imaging based on Si membrane metasurfaces: the near-infrared signal passes through the target, then being converted into the visible signal via the metasurfaces, forming the target image on the CCD camera. (b1–e1) The images of the target and the metasurfaces under white light source illumination. (b2–e2) Transformed visible images of the target via membrane metasurfaces under NIR light illumination.
