We propose a method to generate physical random numbers based on intermittent optical chaos. Intermittent chaotic output is produced in a semiconductor laser subjected to optical feedback embedded in a photonic integrated circuit. This dynamics is ch

We demonstrated a mirrorless terahertz (THz)-wave parametric oscillator (TPO) based on backward optical parametric oscillation. The mirrorless TPO has no cavity mirrors because of inhibit feedback effect inside a periodically poled lithium niobite (P

Publikováno v: Physical Review E. 96

Synchronization properties of chaotic dynamics in two mutually coupled semiconductor lasers with optical feedback embedded in a photonic integrated circuit are investigated from the point of view of their dynamical content. A phenomenon in which the

We report experimentally on the bifurcation cascade leading to the appearance of self-pulsation in a photonic integrated circuit in which a laser diode is subjected to delayed optical feedback. We study the evolution of the self-pulsing frequency wit

International audience; Phase-conjugate optical feedback (PCF) has been largely used as a way to stabilize and reduce the linewidth of laser emission but is also known to generate complex dynamics including self-pulsation and chaos. In contrast to th
