Spontaneous pattern formation with incoherent white light.

Spontaneous pattern formation in a cavity with incoherent light.

We present the first experimental observation of spontaneous pattern formation in a nonlinear optical cavity in which the circulating light is both spatially and temporally incoherent.

Propagation of incoherent "white" light and modulation instability in noninstantaneous nonlinear media.

We develop a theory describing propagation of spatially and temporally incoherent light in noninstantaneous nonlinear media, and predict the existence of modulation instability of "white" light. We find that the modulation instability of white light is fundamentally a collective effect, where all the temporal frequencies participate in the formation of a pattern, and self-adjust their respectiv...

SPATIAL PATTERNS IN NONLINEAR OPTICS Pattern Formation in Optical Cavities With Incoherent Light

terns of this non-resonant system exhibit spatial line narrowing with the increase of feedback, resembling the line narrowing in (resonant) lasers (see Fig. 1). In fact, despite the incoherence of the light, this cavity threshold is analogous to many thresholds in resonant feedback systems with gain.1 In a subsequent paper, we theoretically analyzed a cavity in which the light was also spatiall...

Cavity pattern formation with incoherent light.

We study the propagation dynamics of an incoherent light beam circulating in a passive cavity containing noninstantaneous nonlinear media. It is shown that patterns form in this cavity in spite of spatial incoherence of the light. We show that the pattern formation process is always associated with two consecutive thresholds. The first (instability) threshold is unaffected by the cavity boundar...
