Bright and dark solitons in a photonic nonlinear quantum walk: lessons from the continuum
New Journal of PhysicsWe propose a nonlinear quantum walk model inspired in a photonic implementation in which the polarization state of the light field plays the role of the coin-qubit. In particular, we take profit of the nonlinear polarization rotation occurring in optical

Laguerre-Gaussian modes generated vector beam via nonlinear magneto-optical rotation
Scientific Reports, 2021 Laguerre-Gaussian (LG) beams contain a helical phase front with a doughnut-like intensity profile. We use the LG beam to introduce a rather simple method for generation of a vector beam (VB), a beam with spatially-dependent polarization in the beam cross

Quadrature noise in light propagating through a cold 87Rb atomic gas [PDF]
, 2011 We report on the study of the noise properties of laser light propagating through a cold 87Rb atomic sample held in a magneto-optical trap. The laser is tuned around the Fg = 2 \rightarrow Fe = 1, 2 D1 transitions of 87Rb. We observe quadrature-dependent
