Coupled Meta-Atoms, Plasmon Induced Transparency, Radiative Engineering 

Electromagnetically Induced Transparency (EIT), a spectrally narrow optical transmission window accompanied with extreme dispersion, give rise to dramatically slow down photons and orders of magnitude enhanced optical non-linearities enabling manipulation of light at few photon levels. We have proposed and demonstrated a novel approach based on coupled meta-atoms consisting of meta-materials to construct a homogeneous and scalable medium supporting multispectral EIT-like effect (plasmon induced transparency) that can simultaneously enhance multicolored photon-photon interactions.

Extraordinary Light Transmission 

& On-Chip Light Manipulation

A unique advantage of plasmonic devices is the ability to merge electronic and photonics at nanoscale dimensions. The prospect of such plasmonic devices capable of functioning as actively controlled interconnects is extremely promising. Recently, we have proposed an ultracompact plasmonic resonator structure that enables strong electro-optic modulation of plasmonic signals at subwavelength dimensions.

Monopole Nano-Antennas & Pillars for Optofluidic Trapping, Sorting & Sensing

Most of the plasmonic structures serve for a single operational purpose. Recently, we have introduced a plasmonic nanopillar device platform merging multiple modalities by fusing complementary characteristics of localized and extended surface plasmons. This platform offering biodetection, spectroscopy and optical trapping in a compact form could find wide range of applications in biomedical applications. Furthermore, we demonstrated for the first time that monopole nanoantennas elements can be fabricated in planar geometries for on chip applications.
