Chaotic Cavity News

Beyond the Beam

A review of "Multidimensional Lasers" by Z. Horváth in Optics & Photonics News (July 2012) puts our work on chaotic microdisk lasers in the context of a history that's almost as old as laser physics itself but has only recently become a field in its own right: the study of beam shapes that deviate significantly from the pencil-like straight line geometry of conventional lasers.

The bowtie laser as a book cover

One of my microlaser simulations decorates the cover of this book by Alisa Bokulich, titled "Reexamining the Quantum-Classical Relation" (November 2008).
Another book appearance of our ARC images is the volume Microcavities by A Kavokin, J.J. Baumberg, G. Malpuech and F.P. Laussy, Oxford University Press, (February 25, 2008)
Physical Review Focus (3 September 2004) points to the whispering-gallery microlaser information collected on this website.
PRL Cover The cover of Physical Review Letters, July 18 2003, features our work on microspheres:

Directional tunnel escape from nearly spherical optical resonators

Scott Lacey, Hailin Wang, David H. Foster and Jens U. Nöckel
vol. 91, p. 033902.

The preprint is available here.

For the EXPO 2000 World Fair in Germany, I created a presentation that has been made part of a permanent exhibition maintained by the Max-Planck Society:
The Science Tunnel
(the exhibit is no longer online).
My thesis work helped Yale University recruit graduate students:

One of the projects I started as a postdoc made it to the cover of the annual report of the MPI for Physics of Complex Systems, and also into the "Optics in 2000" section of OPN, see below.

Lucent Technologies' Bell Laboratories (now defunct) featured one of my plots on their "Physical Sciences" web page :

What is an Asymmetric Resonant Cavity anyway ?

The above image is the cover of my PhD thesis, and also appears in a recent online review article on scholarpedia by Martin Gutzwiller.
ARCs are convex resonators whose fractional deformation is so large that the wave equation cannot be solved satisfactorily by perturbation techniques. Shown here as an example is a dielectric cylinder with an oval cross section. Such resonators can be used in lasers or other devices that rely on the existence of long-lived states. The calculated intensity distribution of such a resonator mode is shown here as a false-color image (top of the picture). The key to understanding the intrinsic emission properties of these modes (e.g. their directional emission) is a one-to-one correspondence between waves and rays (red arrow, bottom). The wave field is affected by chaos in the ray dynamics.
unsplit emission
Emission from the points of highest curvature is intuitively expected, and the tangential orientation follows from Snell's law of refraction.
Due to phase space structure, the light here originates slightly away from the high- curvature points, but still tangential to the surface.
