TLDR
In this article, an all-optical beam deflector was proposed to transfer the modulation of the driving beam to the signal beam with power gain and angular deflection rate of 10 mrad/kW. The main component of the deflector is a sample of Cd(S,Se) doped glass and its operation is based on the cross bending effect.Abstract:
We report on the operation of an all‐optical beam deflector whereby the deflected signal beam can be more powerful than the driving beam. Therefore, we have transferred the modulation of the driving beam to the signal beam with power gain and angular deflection rate of 10 mrad/kW. The main component of our deflector is a sample of Cd(S,Se) doped glass and its operation is based on the cross‐bending effect.read more

Spatial soliton-induced guiding by cross-phase modulation
R. de la Fuente,Alain Barthelemy +1 more
TL;DR: In this paper, spatial solitons are used to induce the stable guiding of a weak probe beam in a homogeneous Kerr-type nonlinear media through cross-phase modulation (XPM), and the modes of the induced waveguide are derived from the propagation equation of the probe.
