Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Optofluidic applications with lithium niobate nanowires

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Jae-Woo Choi

We report the hydrothermal synthesis of free-standing lithium niobate nanowires. We show that the versatile properties of bulk lithium niobate such as nonlinear optical effects can be exploited at the nanoscale. We describe the fabrication of polydimethyls ...

Enhanced Second Harmonic Generation in Plasmonic Nanocavities

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

We experimentally demonstrate significantly enhanced second harmonic generation using nanoengineered plasmonic nanocavities of core-shell structures (BaTiO3/Au). An enhancement factor of over 500 is measured in the second harmonic scattering efficiency com ...

Optically Generated Electric Fields by Lithium Niobate Nanowires

Demetri Psaltis, László Forró, Arnaud Magrez, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Jae-Woo Choi, Rita Smajda

We demonstrate that lithium niobate nanowires generate electric fields under 514 nm continuous wave laser illumination. Birefringent media are used to visualize the generated fields in a microfluidic channel. Input laser polarization dependence is shown. ( ...

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

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

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 ...

Harmonic holographic microscopy with circularly polarized excitation

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

We have developed a luminescent marker using the second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocrystals. These nanoparticles are attractive due to their stable, non-saturating and coherent signal with a femtosecond-scale response time ...

Barium titanate nanoparticles used as second harmonic radiation imaging probes for cell imaging

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

Luminescent markers play a key role in imaging techniques for life science since they provide a contrast mechanism between signal and background. We describe a new type of marker using second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocry ...
