We propose a matrix-matrix multiplication by using anisotropic self-diffraction in BaTiO(3). The input matrices are carried by the two incident beams with special Bragg-matched incident angles. The output matrices are produced by anisotropic self-diffraction with the polarization orthogonal to those of the incident matrices. By thresholding the output this architecture is particularly suitable ...

We study the existence and stability of multi-component spatial optical solitons in anisotropic nonlocal photorefractive media. For the case of three components, we find numerically the whole family of composite solitons with two perpendicular dipole components, and show their stability for a wide range of parameters. We confirm our theoretical results by an experimental observation of these no...

We experimentally demonstrate wavelength-preserving spectral phase conjugation for compensating chromatic dispersion and self-phase modulation in optical fibers. Our implementation is based on a temporal imaging scheme that uses time lenses realized by broadband four-wave mixing in silicon waveguides. By constructing a temporal analog of a 4-f imaging system, we compensate for pulse distortions...

We report the first observation of a nonlinear mode in a cylindrical nonlinear FabryPerot cavity. The field enhancement from cavity buildup, as well as the large (3) optical nonlinearity due to resonantly-excited 85Rb vapor, allows the nonlinear mode to form at low incident optical powers of less than a milliwatt. The mode is observed to occur for both the self-focusing and self-defocusing nonl...

We report what is believed to be the first observation of a nonlinear mode in a cylindrical nonlinear Fabry-Perot cavity. The field enhancement from cavity buildup, as well as the large chi((3)) optical nonlinearity that is due to resonantly excited (85)Rb vapor, allows the nonlinear mode to form at low incident optical powers of less than 1 mW. The mode is observed to occur for both self-focus...

We find self-accelerating beams in highly nonlocal nonlinear optical media, and show that their propagation dynamics is strongly affected by boundary conditions. Specifically for the thermal optical nonlinearity, the boundary conditions have a strong impact on the beam trajectory: they can increase the acceleration during propagation, or even cause beam bending in a direction opposite to the in...

This paper first describes the implementation of a protocolindependent self-similar traffic generator in the OPNET modeler. With the support of this traffic generator, we investigate the traffic shaping function at the edge router in optical packet-switched networks. We propose an optical packet assembly mechanism and discuss its impacts on the traffic characteristics. Our simulation results in...

Nondegenerate optical parametric amplifiers can be used to simultaneously phase conjugate and amplify a pulse in a nonlinear optical fiber. The gain in the amplifiers compensates the linear loss in the fiber, while the phase conjugation effectively neutralizes second-order dispersion, self-phase modulation, the Raman self-frequency shift, and Gordon-Haus jitter. If the remaining third-order and...

Self-mixing interferometer is a suitable tool for implementing industrial sensors, with the advantages of optical techniques, such as high accuracy and contactless operation, but at potential very-low cost. This paper describes some techniques recently developed for realizing vibration measurements, based on different signal elaborations and with different performances and applications. Particu...

The influence of temperature on coated (2%) and uncoated Fabry-Pérot laser output in a proposed colorless WDM system with self-seeding via modulation averaging reflector is studied. In particular, the connection between the information about the optical laser output from the laser integrated monitor photodetector and optical power output of the entire system with temperature change of the laser...
