This can give rise to the phenomenon of frequency doubling [1], where an input (pump) wave generates another wave with twice the optical frequency (i.e. half the vacuum wavelength) in the medium. This process is also called second-harmonic generation. Second-harmonic generation - Wikipedia Second harmonic generation (also called frequency doubling or SHG) is a nonlinear optical process in which two photons with the same frequency interact with a nonlinear material, are "combined", and generate a new photon with twice the energy of the initial photons (equivalently, twice the frequency and half the wavelength).

In this paper, the nonlinear effect of second harmonic generation (SHG) in insulator-metal-insulator plasmonic waveguides was investigated. Initially, an IMI plasmonic waveguide was simulated and its SHG effect was considered, then an IMI grating structure was proposed to increase the SHG effect and reduce its loss.
