Measuring the phase velocity of twisted wavefronts
Grace Richard, Holly Lay, Daniel Giovannini +3
Traditionally one defines the speed of a wave as a property of the medium. Recent studies in photonics have challenged this idea, indicating that spatial shaping of the optical wav…
Video recording true single-photon double-slit interference
Reuben S. Aspden, Miles J. Padgett, Gabriel C. Spalding
As normally used, no commercially available camera has a low-enough dark noise to directly produce video recordings of double-slit interference at the photon-by-photon level, becau…
Observation of image pair creation and annihilation from superluminal scattering sources
Matteo Clerici, Gabriel C. Spalding, Ryan E. Warburton +6
The invariance of the speed of light implies a series of consequences related to our perception of simultaneity and of time itself. Whilst these consequences are experimentally wel…
Computer-Generated Holographic Optical Tweezer Arrays
Eric R. Dufresne, Gabriel C. Spalding, Matthew T. Dearing +2
Holographic techniques significantly extend the capabilities of laser tweezing, making possible extended trapping patterns for manipulating large numbers of particles and volumes o…
