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. Rigorous theoretical modelling is developed to describe the propagation, generation and control of electromagnetic fields confined in these nanoscale waveguides. Two configurations are studied thoroughly.

Two sizes of couplers cover the range of frequencies in the cavity and ... slot which results in the highest power density and Elsie Barakat - Academia.edu The structure is fabricated by using electron-beam lithography, dry etching, and chemical mechanical polishing. We report a second-harmonic generation (SHG) enhancement factor of 26 compared to unpatterned x-cut lithium niobate wafer at λpump=1550 nm. US9645045B2 - SHG imaging technique for assessing hybrid FIG. 3B is an image based on second harmonic radiation alone, and FIG. 3C is an image based on third harmonic radiation alone. FIG. 3B shows that second harmonic generation occurs at the poled waveguide 302. FIG. 3C shows third harmonic generation at the gold electrodes 304, 306, likely enhanced by plasmonic effects. This enhancement is Ultrafast Plasmonic Control of Second Harmonic Generation

Abstract We present for the first time second harmonic generation in amorphous stoichiometric Si 3 N 4 waveguides grown via low pressure chemical vapor deposition. An effective second-order susceptibility (χ (2)) is established via the coherent photogalvanic effect.A waveguide was designed to phase match a horizontally (parallel to the waveguide width) polarized hybrid EH 00 mode at 1064 nm Photoinduced χ(2) for second harmonic generation in SPIE Digital Library Proceedings.
