Query: Optical coupling between resonant dielectric nanoparticles and
  dielectric waveguides probed by third harmonic generation microscopy   Localized electromagnetic modes and negligible Ohmic losses dictate the
growing interest in subwavelength all-dielectric nanoparticles. Although an
exhaustive volume of study dealt with interaction of all-dielectric
nanostructures with free-space electromagnetic fields, their performance as
integrated photonics elements remains untackled. We present an experimental
study of optical coupling between a resonant subwavelength silicon nanodisk and
a non-resonant silicon waveguide, as probed by third harmonic generation
microscopy. By placing the nanodisks at different distances from the waveguide,
we observe third harmonic intensity modulation by a factor of up to 4.5. This
modulation is assigned to changes in the local field enhancement within the
nanodisks caused by their coupling to the waveguides and subsequent modulation
of their magnetic-type resonances. Interestingly, although the waveguide
presents an additional loss channel for the nanodisk, we observe an increase in
the local field strength within the nanodisk, as verified by rigorous full-wave
simulations. This work makes a step toward integration of all-dielectric
nanoparticles on photonic chips.
