concepts, recent developments, and future directions
in the field of metatronics.

High performance of a ring resonator and adddrop
multiplexer with ultrasmall ring radius and
sub-wavelength confinement area is reported.
It has been achieved using the silicon-based
hybrid dielectric-loaded plasmonic waveguide
approach.

Center for Research and Education in Optics and
Lasers, Univ. of Central Florida, USA; 3 Department
of Electrical and Computer Engineering, Univ. of
Minnesota, USA. We measure the permittivity
of bulk and film gold samples by spectroscopic
ellipsometry from 200 nm to 20 μm, resolving
inconsistencies on plasmon resonances, lifetime,
and SPP propagation associated with imprecise
current literature values.

We demonstrate broadband modulation instability,
> 40 dB parametric amplification with on-chip
gain bandwidth > 580 nm, and narrowband
Raman-assisted peak on-chip gain exceeding 50
