Investigating the link between a layer thickness and surface relief depth in an azo poly(ether imide)

Surface relief grating formation in photo-responsive azo polymers under irradiation is a long-ago-found phenomenon, but all the factors governing its efficiency are still not fully recognized. Here, ...

Optically induced diffraction gratings based on periodic modulation of linear and nonlinear effects for atom-light coupling quantum systems near plasmonic nanostructures

During the recent decades, nonlinear optical properties of various atomic 1,2,3,4 and other coherent media 5,6 have been well studied due to quantum interference and coherence. As examples and owning ...

Diffraction Limit: The Fundamental Barrier in Optical Microscopy

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...
