The integration of cold atomic systems with optical nanofibres (ONFs) is an increasingly important experimental platform. Here, we report on the spectra observed during a strongly driven, single-frequency, two-photon excitation of cold rubidium atoms near an ONF. At resonance, two competitive processes, namely a higher excitation rate and stronger pushing of atoms from the nanofibre due to resonance scattering, need to be considered. We discuss the processes that lead to the observed two-peak…

Single atoms on an optical nanofiber: a novel work system for slow light

We discuss how subwavelength-diameter silica-fibers, "optical nanofibers", can open new perspectives for manipulating atoms and photons. We explore atom/photon interaction around a nanofiber using

Single Photon Generation and Spectroscopy Using Quantum Dots on Optical Nanofibers

This thesis presents single photon generation and spectroscopy using quantum dots (q-dots) on optical nanofibers. Optical nanofibers are essentially vacuum-clad silica fibers with sub-wavelength

Machine learner optimization of optical nanofiber-based dipole traps for cold 87Rb atoms

In two-color optical nanofiber-based dipole traps for cold alkali atoms, the trap efficiency depends on the wavelength and intensity of light in the evanescent field, and the initial laser-cooling

Machine learner optimization of optical nanofiber-based dipole traps

We use a machine learning optimizer to increase the number of rubidium-87 atoms trapped in an optical nanofiber-based two-color evanescent dipole trap array. Collisional blockade limits the average
