Illustration of the optical ODRW solution of the vector nonlinear fiber-analog system.
(a) Evolution of the temporal wave profiles in the two propagation channels (orthogonal polarizations U and V) of the optical fiber, plotted in a reference frame moving with the group velocity at horizon. (b) Event horizons generated in the propagation channel U in analogy to the flowing river of space in astrophysical black and white hole horizons12. The gradient of the gravitational field across the horizons is analogous to the gradient of the refractive index induced by orthogonally polarized modulated wavefronts. (c) Corresponding laboratory-frame group velocity plotted as a function of frequency, channels U and V exhibit linear group velocities with opposite signs relative to the effective group velocity at horizons.
