I wonder whether one can make low loss waveguides with ALD deposition, using sub wavelength structures. If the mode is highly delocalized, it may not see the granularity as a scattering element. This could be useful if one doesn’t have access to high res ebeams and etching capabilities but just ALD

Exciting webinar which allows us to conclude that the time for the practical use of sub wavelength structures has finally come.
