Diagnostics of femoral head status in humans using high-resolution laser spectroscopy : In vitro studies

Konferensbidrag (refereegranskat)abstract
- Osteonecrosis of the femoral head is caused by inadequate blood supply to the affected bone. The bone decay process due to lacking blood supply would be likely to be accompanied by the formation of gas-filled pores. We have introduced diode laser absorption spectroscopy to successfully detect water vapor signals from pores in the femoral heads retrieved from hip replacement operations in 19 patients. The Gas in Scattering Media Absorption Spectroscopy (GASMAS) variety of tunable laser spectroscopy was employed. The results open up for the possibility of improved diagnostics for a very common disease.

Nonlinear core-shell yagi-uda nanoantenna for highly tunable directive emission

Konferensbidrag (refereegranskat)abstract
- We propose a novel type of tunable Yagi-Uda nanoantenna composed of metal-dielectric (Ag- Ge) core-shell nanoparticles. By choosing the appropriate nanoantenna parameters we excite a Van Hove singularity, supporting high values of directivity and Purcell factor within the same narrow frequency range. Our analysis reveals the possibility of flexible dynamical tuning of the hybrid nanoantenna emission pattern via electron-hole plasma excitation by additional fs-laser signal pulses.

Konferensbidrag (refereegranskat)abstract
- Single-photon detectors with high efficiency, high time resolution, low dark counts and high photon detection-rates are vital for most demanding quantum optics experiments. Combining all performances in a single device has been challenging. Here, we demonstrate a broadband detector with efficiency higher than 92%, over 150 MHz photon detection-rate and dark counts below 130 Hz operated in a conventional Gifford-McMahon cryostat. Furthermore, using our custom made cryogenic amplifiers and optimized detector, we reach a record low jitter of 14.80 ps while maintaining high efficiency.
