Enhanced four-wave mixing in graphene-integrated silicon slot waveguides

Applied Physics Express
Leveraging graphene’s giant third-order nonlinearity and ultrafast response, we experimentally demonstrate a graphene-integrated slot waveguide designed to maximize the effective light–matter interaction. Through four-wave mixing experiments, we achieved

Low-loss silicon slot waveguides and couplers fabricated with optical lithography and atomic layer deposition

, 2011
We demonstrate low-loss silicon slot waveguides patterned with 248 nm deep-UV lithography and filled with atomic layer deposited aluminum oxide. Propagation losses less than 5 dB/cm are achieved with the waveguides.

Polarization-insensitive integration of nanoparticle-on-a-slit cavities with dielectric waveguides for on-chip surface enhanced Raman spectroscopy

npj Nanophotonics
In the nanoparticle-on-a-slit (NPoS) cavity, a variation of the nanoparticle-on-a-mirror geometry, a metallic nanoparticle is placed on a functionalized narrow slit created on a metal plate so that two nanometric-scale gaps enable extreme plasmonic ...
