TLDR
Efficient four-wave mixing (FWM) over micrometer-scale interaction lengths at telecommunications wavelengths on silicon is reported, using an integrated plasmonic gap waveguide that strongly confines light within a nonlinear organic polymer and generating a non linear response so strong that efficient FWM accumulates over wavelength-scale distances.Abstract:
Efficient optical frequency mixing typically must accumulate over large interaction lengths because nonlinear responses in natural materials are inherently weak. This limits the efficiency of mixing processes owing to the requirement of phase matching. Here, we report efficient four-wave mixing (FWM) over micrometer-scale interaction lengths at telecommunications wavelengths on silicon. We used an integrated plasmonic gap waveguide that strongly confines light within a nonlinear organic polymer. The gap waveguide intensifies light by nanofocusing it to a mode cross-section of a few tens of nanometers, thus generating a nonlinear response so strong that efficient FWM accumulates over wavelength-scale distances. This technique opens up nonlinear optics to a regime of relaxed phase matching, with the possibility of compact, broadband, and efficient frequency mixing integrated with silicon photonics.read more

Nanofocusing of Optical Energy in Tapered Plasmonic Waveguides
TL;DR: It is predicted theoretically that surface plAsmon polaritons propagating toward the tip of a tapered plasmonic waveguide are slowed down and asymptotically stopped when they tend to the tip, never actually reaching it (the travel time to the Tip is logarithmically divergent).

TL;DR: It is found that the dominant limiting factor is not the resistive loss of the metal, but rather the intrinsic nonlocality of its dielectric response, which has implications for the ultimate performance of nanophotonic systems.
