- An overall quantum conversion efficiency of 7.8% is achieved by intracavity mixing the signal and idler of a 1.064-μm pumped Rb:PPKTP OPO in BaGa4Se7, generating >0.7 mJ pulse energy at ~7 μm and 100 Hz.

Konferensbidrag (refereegranskat)abstract
- Real-time transmission of 14-GBd 4-PAM signal is demonstrated by combining a commercial 1.55-μm DML with a silicon MRR. BER below the HD-FEC threshold is measured after 26-km SSMF transmission without offline digital signal processing.

Konferensbidrag (refereegranskat)abstract
- We deterministically integrate nanowire quantum-emitters in SiN photonic circuits. We generate single-photons, suppress excitation-laser, and isolate specific transitions in the quantumemitter all on-chip with electrically-tunable filter. Finally, we demonstrate a novel Quantum- WDM channel on-chip.

Konferensbidrag (refereegranskat)abstract
- Efficient nonlinear silicon photonics rely on phase-matching through finewaveguide dispersion engineering. We experimentally demonstrate dynamic dispersion tuningof 800 ps/nm/km in a silicon waveguide ring resonator, by using microelectromechanicalactuation of an adjacent suspended waveguide rim.

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

- 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.
