A nanoplasmonic "transceiver" was assembled to examine the efficiency of coupled plasmonic antennas and their resonance interactions. In particular, plasmonic focusing receiver antenna coupled to transmitting annular antenna having a short central pl

We demonstrate experimentally and theoretically a broad-band enhancement of the spontaneous two-photon emission from AlGaAs at room temperature by plasmonic nanoantenna arrays fabricated on the semiconductor surface. Plasmonic structures with inheren

Broadband plasmonic metamaterials for the near infrared regime are presented, based on multiple small antennas in a unit cell. Rules for building such metamaterials and overcoming the undesired coherent coupling are presented.

Ellipto-Hyperbolic nano-antennas are studied theoretically and experimentally. Self-modes are derived in closed-form, and very high directivity is implied. Ellipto-hyperbolic antennas are under extensive study and only few results are shown here.

We studied experimentally and theoretically resonance characteristics of plasmonic nanoparticle dimers connected by a narrow metal wire. The “conductive” coupling between the particles results in complete redistribution of the surface charge yiel
A method for designing plasmonic particles with desired resonance spectra is presented. The method is based on repetitive perturbations of an initial particle shape while calculating the eigenvalues of the various quasistatic resonances. The method i

New families of plasmonic particles with on-demand resonance design are obtained by applying ‘Evolutionary algorithm’. Other particles were designed to exhibit multipole resonance degeneracy, e.g. collocated dipole-quadrupole, which may be applie

Arrays of plasmonic nano-antennas were fabricated on InGaAs/InP multi quantum well structure. Photo-luminescence enhancement of ×9 was measured in correspondence with nano-antennas resonance, attributed to ×25 increase in radiative recombination ra

Ordered arrays of Au nanodisks, extending into the active layer of organic photovoltaic device exhibit enhanced external quantum efficiency, stemming from resonances of plasmon and nanopatch antennas. Design rules were verified experimentally.

We analyze an inherent nonlinearity of Surface Plasmon Polaritons at the interface of Fermi-Dirac metal plasma, stemming from the depletion of electron density in high-field intensity regions. The derived optical nonlinear coefficients are comparable
