image: New spectroscopic technique for studying nanostructures demonstrates that stibnite nanodots can act as high-optical-quality waveguides and are promising candidates as photoswitchable materials ...

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...
