Chapter 6 Silicon-based active plasmonic devices for on-chip integration

Photonic devices integrated in Si optoelectronic circuits offer less power dissipation and larger bandwidth than those of electronic components, but suffer from a larger footprint due to the fundamental diffraction limit of light in dielectric waveguides and the weak optical response of Si. These two limitations may be overcome by utilizing plasmonics owing to the tight optical mode confinement in plasmonic waveguides. Besides the capability of miniaturization of photonic devices on the nanometer scale, plasmonics also provides the potential to design novel photonic devices due to the incorporation of metal and dielectrics. In this chapter, we present Si-based active ...
