Arrays of quantum dot micropillar lasers are an attractive technology platform for various applications in the wider field nanophotonics. Of particular interest is potential efficiency enhancement as consequence cavity electrodynamics effects which makes them prime candidates next generation photonic neurons neural network hardware. However, optical pumping their power-conversion can be very lo...
The methods producing cold molecules from cold atoms tend to leave molecular ensembles with substantial residual internal energy. For instance, cesium molecules initially formed via photoassociation of cold cesium atoms are in several vibrational levels nu of the electronic ground state. We applied a broadband femtosecond laser that redistributes the vibrational population in the ground state v...
We present a theoretical study of the performance of distributed Raman amplifiers with higher order pumping schemes, focusing in particular on double Rayleigh scattering (DRS) noise. Results show an unexpected significant DRS noise reduction for pumping order higher than third, allowing for an overall performance improvement of carefully designed distributed amplifiers, ensuring a large optical...
