The tremendous progress in nanophotonics at the nanoscale has motivated the development of different imaging techniques. Among them scanning near field optical microscopy (SNOM) and, more recently, super-resolution (SR, awarded by 2014 Nobel Prize). I discussed in details the basic differences between SR and SNOM, pointing out their complementary. Then I overviewed our recent SNOM activity for imaging and engineering at the nanoscale, both for semiconductor nanostructures and photonics nano-resonators [1-7].
