Imaging single photons in non-separable states of polarization and spatial mode
... The quantum nature of physical systems is one of the long-standing mysteries in physical science. The quantum of light, the photon, presents unique opportunities to understand and reconcile our limited understanding of quanta. It is now well accepted that light is made of photons and that a beam of ...

Motion of hot spots in smoothed beams
... This technique of polarization smoothing11 decreases the fraction of intensities that are larger than the averaged intensity, the instantaneous contrast also being reduced, by a factor 1/A2. A third solution would be to reduce the interaction time between hot spots (high laser intensities) and plasm ...

Optical negative refraction by four-wave mixing in thin metallic nanostructures LETTERS *
... This nonlinear negative refraction is experimentally demonstrated using a thin gold film atop a glass substrate; the experimental set-up is illustrated in Fig. 1c. We use two confocal objectives to image the Fourier plane onto CCD cameras such that the propagation directions of the wavevectors in k- ...

Polarization Study 1 Introduction
... polarization angle of the linear polarized light. (Use Jones matrices to see how the HWP act on elliptically polarized light of a given helicity) Now vary the two orientations so that you can plot the change in the angle of the linear polarization as a function of the HWP angle. How does this agree ...

Near-resonant spatial images of confined Bose-Einstein condensates in a 4-Dee... Lene Vestergaard Hau, B. D. Busch, Chien Liu,
... Figure 2 shows the results of such imaging experiments performed on three differently sized condensates in the 4Dee bottle. The probe detuning is 235 MHz and the bias field is 1.5 G. In each case we continue the evaporation process until we are left with a ‘‘pure’’ condensate ~no visible thermal clo ...
