NANOPLASMONICS AND METAMATERIALS LABORATORYRecently,
nanoplasmonics has risen from a relatively obscure science to a prominent
field of research. Electronic interconnects are aspect-ratio limited in speed
(< 20 GHz) and optical interconnects are diffraction-limited in size
(>150 nm for silicon waveguides). Surface plasmons can be envisioned as
quasi-two dimensional electromagnetic excitations, propagating along a
dielectric-metal interface and having the field components decaying
exponentially with penetration depth as small as several nanometers into both
neighboring media. Surface plasmon–based circuits, which merge electronic and
photonic circuits at the nanoscale, may offer the potential to carry optical signals
and electric currents through the same thin metal circuitry, thereby creating
the ability to combine the superior technical advantages of photonics and
electronics on the same chip. Both nanoplasmonics and metamaterials deal with
tailored metal/dielectric and metal/semiconductor nanostructures, e.g.
material with negative permittivity. Our lab at Microsystems Engineering is
focused on experimental and theoretical aspects of this rapidly developing
field ranging from fundamental science to applications and products, such as
nanoplasmonic waveguides, ultrafast active nanoplasmonics, surface
plasmon-enhanced solar cells, 3D metamaterials, 3D invisibility cloaks,
negative refraction, and subwavelength imaging. |
