On the origin of second harmonic generation in silicon ...
Key optical waveguide building blocks such as directional couplers, Y-splitters, and Mach-Zehnder interferometers will be discussed. Second-order nonlinear optical phenomena such as second harmonic generation, the Pockels effect, sum and difference frequency mixing, and optical DESIGN CONSIDERATIONS FOR A SECOND GENERATION … DESIGN CONSIDERATIONS FOR A SECOND GENERATION uses wide-band ridged-waveguide to coaxial transitions, coaxial feedthroughs and external loads. 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
Silicon photonics meets the electronics requirement of increased speed and bandwidth with on-chip optical networks. All-optical data management requires nonlinear silicon photonics.

A frequency multiplier with active linearly tapered slot antennas (LTSAs) has been demonstrated at the second harmonic frequency. In each antenna element, a GaAs monolithic microwave integrated circuit (MMIC) distributed amplifier is integrated with two LTSAs. The multiplier has a very wide bandwidth and large dynamic range. The

second harmonic generation (SHG) processes in LiNbO3 and AlGaAs-based HPW, respectively. However, the non-linear HPW they proposed are not compatible with sili-con photonics. In this Letter, we propose a silicon-organic hybrid plasmonic waveguide (SOHPW) easily amenable to fabrication with a nonlinear polymer (NP) in the slot, as shown in Fig. 1.
