Editorial Foreword to The ECOC 2022 Special Issue
Niels Quack, Hans Georg Limberger, Rachel Grange, Christian Bosshard
The European Conference on Optical Communications (ECOC) is one of the leading conferences in the field of optical communications and its related topics. The 48th edition took place from 18th-22nd September 2022 in Basel, Switzerland. The conference attrac ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Plasmonic heating with near infrared resonance nanodot arrays for multiplexing optofluidic applications
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 ...
Royal Soc Chemistry2014Second harmonic nanoparticles in imaging applications
Demetri Psaltis, Ioannis Papadopoulos, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Jae-Woo Choi, Xin Yang
Nanocrystals with second harmonic response is a new class of nonlinear optical nanoprobes with dramatically different properties from fluorescent agents. Compared with two-photon fluorescence, second harmonic generation is an ultrafast, lossless, and coher ...

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Thomas Jean Victor Marie Lanvin
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 ...
2011In vivo Imaging Using Second-Harmonic Nanoparticles
Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Thomas Jean Victor Marie Lanvin
We demonstrate second-harmonic nanoparticles as nanoprobes for long-term and in vivo imaging. The nanoparticles emitted a stable signal over five-hour continuous excitation and showed great contrast in a living mouse tail at 100 mu m depth. ...
Ieee Service Center, 445 Hoes Lane, Po Box 1331, Piscataway, Nj 08855-1331 Usa2011Bioconjugation of barium titanate nanocrystals with immunoglobulin G antibody for second harmonic radiation imaging probes
Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh
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 ...
Elsevier2010Nonlinear optical properties of core-shell nanocavities for enhanced second-harmonic generation
Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh
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 ...
2010Characterization of the cytotoxicity and imaging properties of secondharmonic nanoparticles
Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh
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 ...

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Grégoire Pierre Jean Laporte
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 ...
2010Digital phase conjugation of second harmonic radiation emitted by nanoparticles in turbid media
Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh
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 ...
