Correlated random bit generation is investigated using three optically injected chaotic semiconductor lasers. Based on a rate-equation model, a continuous-wave injection first perturbs a common laser into chaos. The common laser then optically inject

Chaotic dynamics of a semiconductor laser subject to distributed feedbacks from a fiber Bragg grating (FBG) are investigated through detailed simulations. Because of distributed reflections along the FBG, the approach of FBG feedback performs better

Period-one (P1) dynamics of two lasers under a common injection are perturbed for externally locked frequency-modulated continuous-wave (FMCW) generation. The first laser is injected into P1 dynamics at frequency f 0 , where the dynamics is perturbed

Optical feedback in a semiconductor laser was recently used for photonic microwave square-wave generation by invoking quasiperiodicity for repeated switching between a stable stage of constant intensity and an unstable stage of intensity oscillations

Optical injection into a chaotic laser under feedback is investigated for dimension enhancement. Although injecting a solitary laser is known to be low-dimensional, injecting the laser under feedback is found to enhance the correlation dimension D2 i

Period-one (P1) oscillations in semiconductor lasers are applicable in photonic millimeter-wave (mm-wave) generation. P1 oscillation can be invoked by optically injecting a laser, where the phase noise can be suppressed by modulation. To increase the

Chaotic dynamics of a semiconductor laser subject to optical feedback from a frequency-detuned fiber Bragg grating (FBG) is investigated experimentally and numerically. Although the FBG is similar to a mirror in perturbing the laser into chaos, it is
