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.

Temperature measurement of cold atoms using transient absorption of a resonant probe through an optical nanofibre [PDF]

, 2016
Optical nanofibres are ultrathin optical fibres with a waist diameter typically less than the wavelength of light being guided through them. Cold atoms can couple to the evanescent field of the nanofibre-guided modes and such systems are emerging as ...

Polarisation control for optical nanofibres by imaging through a single lens [PDF]

Journal of Optics, 2019
Abstract 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.

Nondestructive Profilometry of Optical Nanofibers [PDF]

Nano Letters, 2016
Single-mode optical nanofibres are a central component of a broad range of applications and emerging technologies. Their fabrication has been extensively studied over the past decade, but imaging of the final sub-micrometre products has been restricted to destructive or low-precision techniques.

Synthesis of chiral TiO2 nanofibre with electron transition-based optical activity [PDF]

Nature Communications, 2012
The optical chirality induced at the absorption bands due to electronic exciton coupling of the transition dipole moments between chromophores in close proximity is ubiquitous in helical organic materials. However, inorganic materials with optical activity resulting from electronic transitions have not been explored.

Polarization response and scaling law of chirality for a nanofibre optical interface [PDF]

Scientific Reports, 2017
AbstractTwo port optical devices couple light to either port dependent on the input photon state. An important class of two-port devices is that of evanescently-coupled interfaces where chirality of photon coupling can lead to important technological applications.

Complete polarization control for a nanofiber waveguide using directional coupling [PDF]

, 2019
Optical nanofiber waveguides are widely used for near-field delivery and measurement of light. Despite their versatility and efficiency, nanofibers have a critical drawback - their inability to maintain light's polarization state on propagation. Here, we

Scattering approach to two-colour light forces and self-ordering of polarizable particles

New Journal of Physics, 2014
Collective coherent scattering of laser light by an ensemble of polarizable point particles creates long-range interactions, whose properties can be tailored by the choice of injected laser powers, frequencies, and polarizations. We use a transfer matrix

Hard-templating of chiral TiO₂nanofibres with electron transition-based optical activity [PDF]

Science and Technology of Advanced Materials, 2015
The fabrication of optically active inorganic nanomaterials with chiral superstructures attracts attention because of their potential applications in chemical sensing and non-linear optics. Here, we present a facile way to prepare TiO2 nanofibres, in which the nanocrystals are helically arranged into a chiral superstructure.
