We demonstrate increased radiative coupling in periodic arrays of metal nanorods embedded below the substrate surface. The radiative interactions are observed to lead to sharp resonances associated with diffraction. ...
We have demonstrated extraordinary light transmission effect through Fabry-Peacuterot cavities in multilayered plasmonic crystals formed by coupling two physically separated metallic nanohole and nanodisk array layers. Superior field-medium overlap is obse ...
Infrared absorption spectroscopy enabling direct access to vibrational fingerprints of the molecular structure is a powerful method for functional studies of bio-molecules. Although the intrinsic absorption cross-sections of IR active modes of proteins are ...
We introduce a novel sensor scheme combining nano-photonics and nano-fluidics on a single platform through the use of free-standing photonic crystals. By harnessing nano-scale openings, we theoretically and experimentally demonstrate that both fluidics and ...
Extraordinary light transmission effect through Fabry-Perot cavities in 3D plasmonic cystals consisting of two physically separated metallic nanohole and nanodisk array layers is demonstrated. These cavity resonances are highly sensitive to refractive inde ...
We experimentally demonstrate that hybridized nanocavities in optically thick metal films radiate in coherence, and act as an efficient single-polarized plasmonic nano-antenna array. We employ propagating and localized plasmons to enhance polarization cont ...
We measure the lasing dynamics of single and coupled photonic crystal nanocavity array lasers fabricated in the indium gallium arsenide phosphide material system. Under short optical excitation, single cavity lasers produce pulses as fast as 11 ps (full wi ...
We experimentally demonstrate surface excitation of hybridized plasmons in metallic nanocavities. We developed a quasi-static model connecting this observation to plasmonic antenna behavior for extraordinary light transmission effect. ...
It has been theoretically predicted and experimentally shown that circular coaxial aperture arrays have higher transmissivities with respect to simple circular ones. This observation is mainly attributed to the propagating waveguide modes supported by the ...
We analyze the extraordinary transmission effect in the periodic and random nanoaperture arrays in optically thick metal films. Experimental studies are combined with simulations to show that extraordinary transmission effect at midinfrared wavelengths is ...
