Researchers explicitly show how UV-visible, IR, Sum-Frequency Generation (SFG) and Raman spectroscopies all derive from the same tensor formalism, and then draw the consequences for experiments in terms of symmetry-related selection rules. The monitoring of light polarisation states is therefore addressed through multifunctional metamaterials allowing polarisation conversion, from linear to: cross polarisation, left and right circular polarisation with chiral materials such as helical metamaterials. In this Special Issue, invited researchers elaborate on "Recent Advances in Linear and Nonlinear Optics", demonstrating how sensitive light-matter interactions are concerning symmetry.
