We demonstrate that guided mode resonances enhanced second- and third-harmonic generation (SHG and THG) in an azo-polymer resonant waveguide grating (RWG). The enhancement factor for SHG emission is at least 1000 compared to that of a sample without RWG effect.

Surface plasmon amplification by stimulated emission of radiation (spaser) is a nanoscopic quantum generator of coherent local optical fields with high intensity. We will consider the latest development in the theory of spaser and review the large number of experimental data currently available Nanoplasmonics deals with collective electron dynamics on the surface of metal nanostructures, which arises due to excitations called surface plasmons [1, 2]. The surface plasmons localize and concentrate optical energy in nanoscopic regions creating highly enhanced local optical fields. They undergo ultrafast dynamics with timescales as short as a few hundred attoseconds [3]. We will start with a brief overview of the state of nanoplasmonics and its many applications [2].

We have been developing the molecular tweezers that can retrieve a minute amount of molecules from solution such as DNA. Since the retrieved molecules form a bridge between two tips of tweezers, we can examine their electrical characteristics in atmospheric condition. The bridge also serves as a scaffold for nano particles. Figure 1 shows an example of a retrieved DNA wire modified by palladium nano particles of 3nm in diameter. We have found that the palladium particles enhance the electrical conductivity showing 74Ωcm in resistivity. In addition to electromechanical properties, we are interested in optical characterization of retrieved materials by molecular tweezers. To introduce probing light to tweezers' tips, we propose new molecular tweezers integrated with optical waveguides.

Conventional optical components such as lenses and holograms rely on gradual phase shifts accumulated during light propagation to shape light beam. New degrees of freedom in optical design are attained by introducing in the optical path abrupt phase changes over the scale of the wavelength. In this talk, we will discuss the results presented in [1], where a two-dimensional array of plasmonic resonators in form of V-shape antennas with spatially varying phase response and sub-wavelength separation can imprint such phase discontinuities on propagating light.
