This was accomplished by using nanosphere lithography to deposit silver nanoparticles on the ISAM film, tuning the geometry of the particles to make their plasmonic resonances overlap the frequency of optical excitation. An enhancement in the efficiency of second harmonic generation (SHG) by as much as 1600 times was observed. Nanoplasmonic Waveguides Filled with Electro‐Optical In this chapter, nanoplasmonic waveguides filled with electro-optical materials are proposed and discussed.
