Complex phenomena in photonics, in particular, dynamical properties of semiconductor
lasers due to delayed coupling, are reviewed. Although considered a nuisance for a long …

White chaos with a colorless spectral bandwidth of 14 GHz contained within a range of 3 dB
is experimentally generated by optical heterodyning of two external-cavity laser diodes …

Heterodyne generation of parallel random bit streams from chaotic emission of an optically
injected semiconductor laser is investigated. The continuous-wave optical injection invokes …

Conventional tools for measurement of laser spectra (eg optical spectrum analysers) capture
data averaged over a considerable time period. However, the generation spectrum of many …

Complex systems displaying recurrent spike patterns are ubiquitous in nature.
Understanding the organization of these patterns is a challenging task. Here we study …

We investigate the instantaneous behavior of synchronized temporal wave forms in two
mutually coupled semiconductor lasers numerically and experimentally. The temporal wave …

Semiconductor lasers with delayed feedback exhibit two fundamentally different dynamical
states: weak and strong chaos. We characterize experimentally the mechanism for the …

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 …

We describe a method to infer signatures of determinism and stochasticity in the sequence
of apparently random intensity dropouts emitted by a semiconductor laser with optical …

We perform phase-space tomography of semiconductor laser dynamics by simultaneous
experimental determination of optical intensity, frequency, and population inversion with …
