Throughout optics and photonics, phase is normally controlled via an optical path difference. Although much less common, an alternative means for phase control exists: a geometric phase (GP) shift occ...
Imagine watching the World Cup or the Super Bowl in 3-D in the comfort of your own home. That option may be available sooner than you think. With support from the National Science Foundation (NSF), op...
On-demand Optical Tweezers Using Computer-generated Phase Holograms
Holographic optical tweezers Spatial light modulator Time-multiplexing

We have developed an optical tweezers system by on-demand operation. In this work, we achieved real-time displacement of a trapped particle together with a fixed trapped array of particles. The displa...
