We employ nano-scale imaging and spectroscopy techniques to elucidate polariton characteristics as a function of the complex refractive index of the substrate. Although higher-order polariton modes exhibit wavelengths weakly sensitive to the environment, the principal mode strongly depends on the substrate dielectric constant.

Fast optical limiters are needed to protect sensors from intense short laser pulses. An optical limiter design based on a conducting-oxide grating with a large nonlinear refractive index at the plasma frequency is proposed and investigated.

Phased array antenna system is evaluated in the 90GHz band using fiber-dispersion-based true time delay. Phase differences are induced by transmission of the optical fiber, without any additional equipment. Beam steering angle with a range of 5 degrees is successfully demonstrated with four horn-antenna elements.

We fabricate and functionalize silicon-nitride microring for detecting attachment of Neuropeptide Y (NPY) molecules, commonly associated with human stress. For 4 Mg/ml NPY concentration in aqueous solution we experimentally observe ∼0.4 nm resonance shift.

To improve the efficiency of GaSb-based mid-wave infrared LEDs, we investigated the enhanced spontaneous emission by a dipole in a thin slab numerically. A Purcell factor around 5 was achieved by combining a thin waveguide and plasmonic grating.

High-resolution optical optical diagnostics have long been used to characterize the expansion and electron density of dense laser plasmas. We describe recent studies of remotely-created dense laser plasmas produced by laser air-filaments that project high intensity laser light to distances of a kilometer.

An array of seven fiber collimators with transmission ~99.9% was tested with 1.99 kW per channel. Truncated radiation was disposed through output collimating lenses by re-directing Gaussian beam tails with interior holey micro-lenses. For range of truncation of 5-29% cooling was not necessary. Beam quality in the far-field M2 ~1.2.

3D-configurated donor-acceptor stereoisomers cis-cup-tris[C60>(DPAF-C9)] were found to exhibit photoswitchable dielectric amplification phenomena using white LED light excitation at GHz frequency. The observation was correlated to the photoactivation of the Au-layer resulting in plasmonic energy to enhance photoinduced intramolecular e−-transfer from DPAF to a C60> moiety. Accumulated plasmonic resonance energy at the near-field surface was effective to distribute negative charges along the outer (C60>)-derived fullerosome shell layer of the trilayered NPs.
