The visible second harmonic of the idler output from a noncollinear optical parametric amplifier was compressed using adaptive dispersion control with a deformable mirror. The amplifier was pumped by and seeded in the signal path by a common 400 nm second-harmonic pulse from a Ti:sapphire regenerative amplifier. Thus, both the idler output and the second harmonic of the idler were passively car...

We discuss how all-optical signal processing might play a role in future all-optical packet switched networks. We introduce a concept of optical packet switches that employ entirely all-optical signal processing technology. The optical packet switch is made out of three functional blocks: the optical header processing block, the optical memory block and the wavelength conversion block. The oper...

In dynamic equilibrium trade models, the common assumption that asset markets are complete implies that correlations of consumption across countries should be quite high. In contrast, measured consumption correlations tend to be rather low. While some suggest this implies that asset market incompleteness is a fundamental feature determining international trade dynamics, this paper provides an e...

The last five years in Australia have seen the intensification of activity around teacher standards. There have been a number of initiatives at the national level, including the development of standards for accomplished teachers of Mathematics, Science and English. A number of state education systems have also undertaken work in this area—for example in Western Australia (EDWA 2001) and Queensl...

We present the development of a monolithically integratable optical isolator. The device is a semiconductor optical amplifier with magnetized ferromagnetic metal contact. 12.7dB isolation and optical transparency are demonstrated. The spectral dependence is studied. ©2005 Optical Society of America OCIS codes: (230.3240) Isolators; (250.5980) Semiconductor optical amplifiers; (230.3810) Magneto...

We report the first numerical demonstration of the generation of multiple superradiance pulses in a slippage-dominant freeelectron laser amplifier. In this simulation, the 1 and 2 multiple radiation-pulses are created from the deformation of the longitudinal phase space. Our simulation confirmed controllability over the temporal profile of these pulses, and paves the way for applying this techn...
