Figure 3 | Characterizations of bright-field imaging and edge-enhanced imaging.

Caption

a-c, Experimental xz-plane (a) and xy-plane (b) intensity distributions and bright-field imaging (c) at the nonresonant wavelength of 1500 nm and the resonant wavelength of 1560 nm. d, Experimental setups for edge-enhanced imaging. e, Experimental output images of reference, Dip 1, and Dip 2. The reference is the original object imaging without metasurface. Dips 1 and 2 are the scenarios with metasurface filtering. Scale bars are 20 μm. f, Intensity distributions along the white dashed lines.
