Disentangling a Nonlinear Oscillator Array Dr. Murray Hamilton, University of Adelaide, Australia Multimode lasers are a particularly convenient example of nonlinear oscillator arrays for fundamental studies. The reason for this is that they are arrays in frequency, rather than coordinate, space. Comparison of the transfer functions to intensity noise spectra of individual modes shows intriguing features that indicate highly nontrivial effects of the perturbations from the lasers environment. This could prove particularly important in the context of massively parallel processing, fast memory access and shared memory systems. The arguments for using optical rather than eletrical links will be presented along with the various devices upon which such systems rely.
All glasses show universal properties at low temperatures.
Such systems allow for designer glasses, whereby the dopant ion mass, size and valency can be altered in a controlled fashion. There is a renewal in the search of new laser materials from uv to ir, especially of nonlinear materials to cover new capabilities of laser wavelengths. Interesting perspectives concern also the development of quasi-phase matching in periodically poled medium. The field of solid state physics was based on the study of single crystal materials which exhibit long-range order. A new field has emerged in the last decade, that of nanostructures, materials which have a large fraction of surface atoms.
