Optical forces and torques on eccentric nanoscale core-shell particles
Qiang Sun, Kishan Dholakia, Andrew D Greentree
The optical trapping and manipulation of small particles is an important tool for probing fluid properties at the microscale. In particular, microrheology exploits the manipulation…
Transverse optical binding for a dual dipolar dielectric nanoparticle dimer
Xiao-Yong Duan, Graham D. Bruce, Kishan Dholakia +3
The physical origins of the transverse optical binding force and torque beyond the Rayleigh approximation have not been clearly expressed to date. Here, we present analytical expre…
Speckle-based determination of the polarisation state of single and multiple laser beams
Morgan Facchin, Graham D. Bruce, Kishan Dholakia
Laser speckle is generated by the multiple interference of light through a disordered medium. Here we study the premise that the speckle pattern retains information about the polar…
