Description
We have developed a methodology for manufacturing alkali-metal vapour cells with internal confinement dimensions down to hundreds of nanometers (generally less than the probe laser wavelength). We envisage our nano-cells as a platform for fundamental atom-light interaction experiments, as well as for potential technological applications. Our manufacture process is versatile and our fused-silica cells are robust. The figure below, from our recent paper [Cutler et al, Phys. Rev. Applied 14, 034054 (2020)], shows a schematic and photograph of one of our nano-cells, as well as some example etched nano-structures. Similar cells have already been used to investigate the cooperative Lamb shift in a dense atomic vapour, measure the atom-surface van der Waals interaction, and to study the spectral response and transit time broadening of the vapour under evanescent excitation. This poster will describe recent experiments and developments using our nano-cell platform.
