Polarisation control for optical nanofibres by imaging through a single lens [PDF]
Polarisation control for optical nanofibres by imaging through a single lens, 2019 We present a simple method for controlling the polarisation state of light at the waist of a single-mode optical nanofibre. The method consists of complete polarisation compensation based on imaging scattered light from inherent inhomogeneities both on the fibre surface and in the glass material itself.

Optical transport of sub-micron lipid vesicles along an optical nanofibre
, 2020 Enhanced manipulation and analysis of bio-particles using light confined in nano-scale dielectric structures has proceeded apace in the last several years. Small mode volumes, along with the lack of a need for bulky optical elements give advantages in sensitivity and scalability relative to conventional optical manipulation.

Measurements on release–recapture of cold 85Rb atoms using an optical nanofibre in a magneto-optical trap [PDF]
Optics Communications, 2013 Abstract We have performed release–recapture temperature measurements of laser-cooled 85Rb atoms using an optical nanofibre (ONF) in a magneto-optical trap (MOT). The effects of changing the cooling laser light-shift parameter on the temperature of the cold atoms and spring constant of the trap are studied.

Interaction of two Rydberg atoms in the vicinity of an optical nanofibre [PDF]
Interaction of two Rydberg atoms in the vicinity of an optical nanofibreWe consider two rubidium atoms, prepared in the same S or P Rydberg states, near an optical nanofibre, and we determine their van der Waals interaction potential as a function of their separation along the nanofibre axis, their distance to the nanofibre axis, and their relative azimuthal angle. We compare results obtained through direct diagonalisation

Characterisation and spectroscopy of laser-cooled atoms with an optical nanofibre
, 2013 In this thesis, a magneto-optical trap setup is used to laser cool and confine a cloud of 85Rb. The cloud typically contains 108 atoms in a 1 mm3 volume at a temperature in the region of the Doppler Limit (146 _K for 85Rb). To study the cold cloud, a subwavelength optical fibre - a nanofibre, or ONF - is positioned inside the cloud. The ONF can be used
