Design and fabrication of highly efficient non-linear optical devices for implementing high-speed optical processing [PDF]
, 2002 We present the design and fabrication of micro-cavity semiconductor devices for enhanced Two-Photon-Absorption response, and demonstrate the use of these devices for implementing sensitive autocorrelation measurements on pico-second optical ...

FEBS Open Bio, EarlyView.Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells
FEBS Open Bio, EarlyView.Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

Multi-Color Two-Photon Microscopic Imaging Based on a Single-Wavelength Excitation
Biosensors, 2022 Two-photon probes with broad absorption spectra are beneficial for multi-color two-photon microscopy imaging, which is one of the most powerful tools to study the dynamic processes of living cells.

Stochastic and deterministic absorption in single-photon interference experiments
Physical Review A, 1997 We performed single-photon interference experiments with neutral density filters and slow beam choppers to confirm the difference between stochastic and deterministic absorption and obtained results that agreed with the case of neutron-interference experiments and quantum theory.

Advanced Engineering Materials, EarlyView.Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.

A high-rate source for single photons in a pure quantum state
New Journal of Physics, 2013 We report on the efficient generation of single photons, making use of spontaneous Raman scattering in a single trapped ion. The photons are collected through in-vacuum high-numerical-aperture objectives. Photon frequency, polarization and temporal shape

Realization of a Universal Quantum Gate Set for Itinerant Microwave Photons
Physical Review X, 2022 Deterministic photon-photon gates enable the controlled generation of entanglement between mobile carriers of quantum information. Such gates have thus far been exclusively realized in the optical domain and by relying on postselection.
