Fig. 13.23 Experimental verification of broadband performance of the magnifying Maxwell fisheye
lens. a, b Images taken at λ = 515 nm. c, d Images taken at λ = 633 nm. The scale bar length is
5 µm in all images
These simulations demonstrate excellent mode-sorting performance of a micrometerscale Maxwell fisheye lens. As illustrated in Fig. 13.25a, symmetric excitation of the
input waveguide mostly couples the output power to the central single mode waveguide on the right side of the structure. On the other hand, as shown in Fig. 13.25b,
asymmetric excitation of the input waveguide leads to propagation of higher spatial
modes, which are channeled primarily into the side output waveguides.
13.6 Conclusion
Experimental and theoretical results discussed in this chapter strongly indicate that
both major recent developments in far-field optical microscopy—nonlinear superresolution techniques and linear techniques based on plasmonic and optical metamaterials—are quickly moving the resolution scale of far-field optical microscopy
down toward the 10 nm level. While fabrication of 3D photonic metamaterials faces
numerous technological challenges, many concepts and ideas in the optics of meta-
