- Independent polarisation control of multiple optical trapsDaryl Preece
Department of Physics and Astronomy, Kelvin Building, University of Glasgow, Glasgow G12 8QQ, United Kingdom
Opt Express 16:15897-902. 2008..We demonstrate the functionality of the system by controlling the rotation and orientation of birefringent vaterite crystals within holographic optical tweezers...
- Increasing trap stiffness with position clamping in holographic optical tweezersDaryl Preece
Department of Physics and Astronomy, SUPA, University of Glasgow, G12 8QQ, UK
Opt Express 17:22718-25. 2009..This reduction relies on the generation of holograms at high speed. We present software capable of calculating holograms in under 1ms using a graphics processor unit...
- Light beams with fractional orbital angular momentum and their vortex structureJörg B Götte
Department of Physics and Astronomy, SUPA, University of Glasgow, Glasgow G12 8QQ, UK
Opt Express 16:993-1006. 2008..We believe that their structural stability makes these beams ideal for quantum information processes utilising fractional OAM states...
