Absorption enhancement of molecules in the weak plasmon-exciton coupling regime
(Optical Society of American (OSA), 2014)We report on the experimental and theoretical investigations of enhancing the optical absorption of organic molecules in the weak plasmon-exciton coupling regime. A metal-organic hybrid structure consisting of dye molecules ... -
All-chalcogenide glass omnidirectional photonic band gap variable infrared filters
(AIP Publishing, 2009)We report on the design, fabrication, and characterization of spatially variable infrared photonic band gap filter that consists of thermally evaporated, high refractive indexcontrast, amorphous chalcogenide glass multilayers. ... -
Critical coupling in plasmonic resonator arrays
(Optical Society of America, 2011)We report critical coupling of electromagnetic waves to plasmonic cavity arrays fabricated on Moiré surfaces. Dark field plasmon microscopy imaging and polarization dependent spectroscopic reflection measurements reveal ... -
Electrically controlled resistive switching assisted active ultra-broadband optical tunability in the infrared
(2013)We present an electrically tunable optical device with ultra-broadband tunability operating in 2-10 μm spectrum. We also, for the first time, optically observe resistive switching behavior in reflection measurements under ... -
Slowing surface plasmon polaritons on plasmonic coupled cavities by tuning grating grooves
(American Institute of Physics, 2010)We investigate slow surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by coupled plasmonic cavities on Moiŕ surfaces. We demonstrate controlling the group velocity and dispersion of the SPPs by varying ... -
Ultra hybrid plasmonics: Strong coupling of plexcitons with plasmon polaritons
(OSA - The Optical Society, 2015)We report a ternary-coupled plasmonic system consisting of excitons of J-aggregated dye, localized surface plasmon polaritons of Ag nanoparticles, and propagating surface plasmon polaritons of continuous Ag film. J-aggregate ...
