Noiselike pulses with a broadband spectrum generated from an erbium-doped fiber laser.
A theoretical model indicates that this mode of operation can be explained by the internal birefringence of the laser cavity combined with a nonlinear transmission element and the gain response of the fiber amplifier.
Discrete Solitons in Optics
Collapse of optical pulses.

Under the combined effect of diffraction, anomalous dispersion, and nonlinear refraction, an optical pulse can collapse simultaneously in time and space. Such a collapse could yield short pulses with…
Discrete Spatial Optical Solitons in Waveguide Arrays
We report the observation of discrete spatial optical solitons in an array of 41 waveguides. Lightwas coupled to the central waveguide. At low power, the propagating ﬁeld spreads as it couples tomore…
Nonlinear scanning laser microscopy by third harmonic generation
Third harmonic generation near the focal point of a tightly focused beam is used to probe microscopical structures of transparent samples. It is shown that this method can resolve interfaces and…
Ghost imaging with a single detector
We experimentally demonstrate pseudothermal ghost imaging and ghost diffraction using only a single detector. We achieve this by replacing the high-resolution detector of the reference beam with a…
Anderson localization and nonlinearity in one-dimensional disordered photonic lattices.
An intermediate regime is found in which the ballistic and localized components coexist while diffusive dynamics is absent and evidence is found for a faster transition into localization under nonlinear conditions.
High-NOON States by Mixing Quantum and Classical Light
“high-NOON” states are generated by multiphoton interference of quantum down-converted light with a classical coherent state in an approach that is inherently scalable and with a visibility higher than that obtainable using classical light only.
Discretizing light behaviour in linear and nonlinear waveguide lattices
Light propagating in linear and nonlinear waveguide lattices exhibits behaviour characteristic of that encountered in discrete systems, which can be exploited to achieve diffraction-free propagation and minimize the power requirements for nonlinear processes.
Compressive ghost imaging
We describe an advanced image reconstruction algorithm for pseudothermal ghost imaging, reducing the number of measurements required for image recovery by an order of magnitude. The algorithm is…
