Plasmonic heating with near infrared resonance nanodot arrays for multiplexing optofluidic applications

Rachel Grange

In this work, we show local laser-induced heating in fluids with gold nanodot arrays prepared by electron-beam lithography that cover resonances in the near infrared spectral range from 750 nm to 880 nm. We utilize two approaches to demonstrate thermal eff ...

Imaging with second-harmonic radiation probes in living tissue

Rachel Grange, Demetri Psaltis, Thomas Jean Victor Marie Lanvin, Chia-Lung Hsieh, Ye Pu, Ye Pu

We demonstrate that second-harmonic radiation imaging probes are efficient biomarkers for imaging in living tissue. We show that 100 nm and 300 nm BaTiO3 nanoparticles used as contrast markers could be detected through 50 mu m and 120 mu m of mouse tail ti ...

Imaging through turbid layers by scanning the phase conjugated second harmonic radiation from a nanoparticle

Rachel Grange, Demetri Psaltis, Chia-Lung Hsieh, Ye Pu, Grégoire Pierre Jean Laporte, Ye Pu

We demonstrate imaging through a turbid layer by using digital phase conjugation of the second harmonic field radiated from a beacon nanoparticle. We show that the phase-conjugated focus can be displaced from its initial position by illuminating the same r ...

Second harmonic generation from nanocrystals under linearly and circularly polarized excitations

Rachel Grange, Demetri Psaltis, Chia-Lung Hsieh, Ye Pu, Ye Pu

We study second harmonic generation (SHG) from noncentrosymmetric nanocrystals under linearly polarized (LP) and circularly polarized (CP) excitations. Theoretical models are developed for SHG from nanocrystals under both plane-wave and focused excitations ...

Characterization of the cytotoxicity and imaging properties of secondharmonic nanoparticles

Rachel Grange, Demetri Psaltis, Chia-Lung Hsieh, Ye Pu, Ye Pu

We develop second-harmonic nanoparticles as the contrast agents for cell imaging. Second-harmonic nanoparticles show promise as cell imaging probes due to their non-bleaching, non-blinking, and coherent signal. Nanoparticles of noncentrosymmetric crystal s ...

Nonlinear optical properties of core-shell nanocavities for enhanced second-harmonic generation

Rachel Grange, Demetri Psaltis, Chia-Lung Hsieh, Ye Pu, Ye Pu

A nonlinear optical plasmonic core-shell nanocavity is demonstrated as an efficient, subwavelength coherent light source through second-harmonic generation. The nonlinear optical plasmonic nanocavity incorporates a noncentrosymmetric medium, which utilizes ...

Three-dimensional harmonic holographic microcopy using nanoparticles as probes for cell imaging: erratum

Rachel Grange, Demetri Psaltis, Chia-Lung Hsieh, Ye Pu, Ye Pu

An error was made in calculating the polarization dependent second harmonic response of barium titanate nanoparticles. We have corrected the error and repeated the comparison with the experimental results. (C) 2010 Optical Society of America ...

Bioconjugation of barium titanate nanocrystals with immunoglobulin G antibody for second harmonic radiation imaging probes

Rachel Grange, Demetri Psaltis, Chia-Lung Hsieh, Ye Pu, Ye Pu

The second harmonic generation (SHG) active nanocrystals have been demonstrated as attractive imaging probes in nonlinear microscopy due to their coherent, non-bleaching and non-blinking signals with a broad flexibility in the choice of excitation waveleng ...

Digital phase conjugation of second harmonic radiation emitted by nanoparticles in turbid media

Rachel Grange, Demetri Psaltis, Chia-Lung Hsieh, Ye Pu, Ye Pu

We demonstrate focusing coherent light on a nanoparticle through turbid media based on digital optical phase conjugation of second harmonic generation (SHG) field from the nanoparticle. A SHG active nanoparticle inside a turbid medium was excited at the fu ...
