The quantum-limited line width of a laser cavity is enhanced above the Schawlow–Townes value by the Petermann factor K, due to the non-orthogonality of the cavity modes. We derive the relation between the Petermann factor and the residues of poles of the scattering matrix and investigate the statistical properties of the Petermann factor for cavities in which the radiation is scattered chaotically. For a single scattering channel we determine the complete probability distribution of K and find… Expand

Correlation Widths in Quantum-Chaotic Scattering
An important parameter to characterize the scattering matrix S for quantum- chaotic scattering is the width corr of the S-matrix autocorrelation function. We show that the "Weisskopf estimate" d=(2�)Expand
Model for chaotic dielectric microresonators
We develop a random-matrix model of two-dimensional dielectric resonators which combines internal wave chaos with the deterministic Fresnel laws for reflection and refraction at the interfaces. TheExpand
Signatures of classical diffusion in quantum fluctuations of two-dimensional chaotic systems.
We consider a two-dimensional (2D) generalization of the standard kicked rotor and show that it is an excellent model for the study of universal features of 2D quantum systems with underlyingExpand
General linewidth formula for steady-state multimode lasing in arbitrary cavities.
TLDR
It is found that low cavity quality factor, combined with significant dielectric dispersion, can cause substantial deviations from the Shawlow-Townes-Petermann theory. Expand
Nearest level spacing statistics in open chaotic systems: generalization of the Wigner surmise.
TLDR
The theoretical results give a clear physical meaning of the modifications on the spacing distributions produced by the coupling to the environment, and general expressions of the spacing distribution for any number of channels, valid from weak to strong coupling are proposed. Expand
Ab initio multimode linewidth theory for arbitrary inhomogeneous laser cavities

Scattering, reflection and impedance of waves in chaotic and disordered systems with absorption

TLDR
The Petermann excess-spontaneous-emission factor is taken into account and it is found that the quantum-noise fluctuations or Schawlow-Townes fluctuations in the output spectrum of a laser oscillator will be multiplied by this excess noise factor. Expand
