Abstract
Second Harmonic Generation (SHG) is a nonlinear process through which two photons with the same frequency, generate a new photon with twice the initial frequency [1]. Harmonic generation is on the basis of many of light technologies developed to date, for both commercial and research purposes. Currently new functionalities and applications are being realized for optical characterization and manipulation, sensing and control of light. This work is precisely devoted to such topics. We present a method that allow us to envisage nanodevices for control and generation of light at the nanoscale based on coherently combining different light harmonics.
