Fig. 13.25 COMSOL Multiphysics simulations of a Maxwell fisheye-based mode sorter. a Symmetric excitation of the multimode input waveguide leads to the output power being channeled
into the central single mode output waveguide. b Asymmetric excitation of the multimode waveguide leads to propagation of higher spatial modes, which are channeled preferentially into the side
single mode waveguides. The spatial dimensions of the magnifying Maxwell fisheye lens in these
simulations are the same as in Fig. 13.1
materials may be tested much easier in two spatial dimensions using planar optics of
SPPs and the lithographically defined tapered waveguide geometries. The 2D geometries and devices described above may be used in various superresolution microscopy,
waveguiding, and laser cavity schemes. We have reviewed various examples of 2D
super-resolution imaging devices, which are reasonably easy to fabricate and study.
These devices exhibit spatial resolution of at least 70 nm, which far exceed resolution of conventional optical microscopy. Moreover, utilization of well-known
digital image recovery techniques enables further improvement of resolution of far-
