The chaotic behavior due to the non-linearity present in a time-delayed feedback system has potential applications for secure optical communication and encryption. Here, a laser diode with phase-conjugate feedback is reported with state-of-the-art br

Abstract We theoretically analyze the waveguiding structures photo-induced by two incoherent counter-propagating Bessel beams (BBs) in a biased photorefractive crystal. We demonstrate that the cross-coupling of two BBs enables adressable channels and

Abstract We demonstrate the formation of a two dimensional Airy beam soliton in a photorefractive crystal. By simply varying the nonlinearity strength we identify several scenarios showing the coexistence between an Airy beam and the emerging soliton

Slowdown of Gaussian “dark pulses” in photorefractive crystal using a two-wave mixing method is shown at room temperature. In agreement with our theoretical model, the experiment shows the dependence of the dark pulse delay and the group velocity

In this work, we experimentally and theoretically report on optical comb dynamics in VCSELs induced by optical injection. We show that injection of a narrow comb with parallel, orthogonal or arbitrary polarization can sustain two polarization comb dy

In this Letter, we experimentally demonstrate a method to improve the bandwidth and flatness of chaos from a laser diode using the optical injection of a frequency comb. Our results show that the injection of an optical frequency comb into a laser di
