IR-green-visible-images

Caption

Through the sum-frequency generation (SFG) nonlinear optical process, two incident photons, one of them in the IR spectrum, interact within the metasurface to generate emission at green visible frequencies. More importantly, an IR image of a target is mixed with a second beam, within the metasurface, generating a green visible image via SFG. Optical microscope images of different transverse positions of the target (left-hand side) and their corresponding up-converted images (right-hand side).
