Diffraction-less propagation beyond the sub-wavelength regime: a new type of nanophotonic waveguide

HIGHLIGHTS

• who: Carlos Alonso-Ramos from the Centre for Nanoscience and Nanotechnology, CNRS, Universitu00e9 Paris-Sud, Universitu00e9 Paris-Saclay, C N, Orsay, Palaiseau, France Centre for Optical and Electromagnetic Research, Zijingang Campus, Zhejiang University have published the article: Diffraction-less propagation beyond the sub-wavelength regime: a new type of nanophotonic waveguide, in the Journal: Scientific Reports Scientific Reports of 13/03/2019
• what: The authors propose a radically different approach to suppress diffraction effects in long-period gratings with high index contrast. Specifically, the authors show that design of the grating radiation provides selective cancellation . . .
