Chris Greene Lisa Wiese Nebraskaadvisor: Applying an analogous phase-space analysis to nonspherical lasing microdroplets, we explained their experimentally observed anisotropic emission [ 3031 ].

In the ray picture, the light circulates around the disk in a series of total internal reflections see Fig.

We have Brett esry thesis out such calculations for dielectric microcylinders or disks [ 14 ] at deformations well beyond the reach of a shape perturbation theory [ 1516 ] that had been previously applied to microdroplets.

Micro-optics and quantum chaos, two fields with rather different objectives, have thus found a promising connection from which optical device design can benefit and new theoretical questions emerge.

From to he was a senior staff consultant with Terra Tek in Salt Lake City, Utah, developing a new fracture toughness test method. For the analogous WG modes in fused-silica microspheres, record Q-factors well above have been measured at optical wavelengths [ 67 ]. A nonseparable wave equation means that rays move along chaotic trajectories.

The anisotropic structure of the SOS in the neighborhood of causes rays to escape preferentially at certain with only slightly below [ 28 ]. He continued his studies in atomic physics as a graduate student at the University of Colorado, working with Chris H.

Sincehe has been president of his own company, Valyn International, where he continues to contribute innovations to the VISAR Brett esry thesis wave instrumentation techniques he pioneered in the s. However, in order to decide for which shapes it is worthwhile to perform numerical or real experiments in the first place, and what phenomena to expect, we resort to the explanatory and predictive power of the ray picture.

Our eikonal theory not only provides the frequency shifts of chaotic WG resonances [ 26 ], but also relates each quantized WG mode to a particular adiabatic invariant curve AIC in the SOS.

He enrolled in physics at Hamburg University inand spent a year at Oregon State University in Corvallis as a graduate exchange student. Barker of Valyn International has been selected as the recipient of the Shock Compression Science Award, to be presented during the Shock Compression of Condensed Matter meeting in Snowbird, Utah, later this month.

These microdisk lasers rely on ring-shaped modes localized near the dielectric interface with the surrounding lower-index medium e.

He spent 27 years at Sandia National Laboratories, making important innovations in time-resolved shock-wave instrumentation, and applying new techniques for measuring the dynamic properties of condensed materials.

While at JILA, Esry collaborated on a number of problems outside the scope of his primary thesis work, the many-body theory of Bose-Einstein condensation.

This unavoidable outcoupling loss is analogous to quantum tunneling and its rate is correspondingly small.

His current research interests include few-body problems and time-dependent phenomena as well as Bose-Einstein condensates.

The Award Committee consisted of: Besides microlasers with different active materials [ 1011 ], there is a wide range of other applications that can benefit from the long-lived metastable states in such dielectric resonators [ 1213 ]. This is because the wave equation is not separable when no good quantum numbers such as angular momentum are preserved, and a typical mode then contains admixtures of many different L.

At large deformations, on the other hand, chaotic diffusion toward the escape condition can be suppressed by wave interference, leading to dynamical localization [ 26 ].

This slow diffusion in is directed toward lower values, but the intermediate almost-regular motion can be characterized by an adiabatic invariant for which we then perform a semiclassical quantization in the spirit of the eikonal EBK approach [ 26 ].

Finally, comparing with numerical wave solutions, we can extract wave corrections to the ray theory, thereby identifying the physics that is not contained in an essentially classical model for the metastable states.

Semiclassical quantization of course yields the resonance frequencies, too - this has historically been its main objective [ 17181920 ].

Since then he has been a staff member at the Max-Planck Institut in Dresden, continuing to investigate microresonators. This is because a change in n may place in a part of the SOS where island structure strongly modifies the chaotic diffusion of WG rays [ 29 ]. He completed his German Diploma degree in Hamburg with a thesis on magnetotransport in semiconductor microsctructures before beginning PhD studies at Yale University in The first prize was shared between myself and Brett Esry.

As a dramatic consequence, we predict that the emission profile of an oval cylinder resonator can depend strongly on its refractive index, even if all other parameters i.

This defines our agenda:Three physicists were honored recently with awards from the APS. Brett Esry and Jens Nöckel, both recent PhDs, were selected as co-recipients of the Award for Outstanding Doctoral Thesis Research in Atomic, Molecular or Optical Physics during the APS Centennial Meeting in Atlanta.

And Lynn M. The work presented in this thesis focuses on controlling this light{molecule interaction in such a way that we can preferentially dissociate the molecule to a desired nal product.
