Quantum limit of the laser linewidth in chaotic cavities and statistics of residues of scattering matrix poles
H. Schomerus, K. M. Frahm, M. Patra +1
The quantum-limited linewidth 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 t…
Propagation of squeezed radiation through amplifying or absorbing random media
M. Patra, C. W. J. Beenakker
We analyse how nonclassical features of squeezed radiation (in particular the sub-Poissonian noise) are degraded when it is transmitted through an amplifying or absorbing medium wi…
Large Petermann factor in chaotic cavities with many scattering channels
K. Frahm, H. Schomerus, M. Patra +1
The quantum-limited linewidth 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. The average…
Photon shot noise
C. W. J. Beenakker, M. Patra
A recent theory is reviewed for the shot noise of coherent radiation propagating through a random medium. The Fano factor P/I (the ratio of the noise power and the mean transmitted…
Quantum-limited linewidth of a chaotic laser cavity
M. Patra, H. Schomerus, C. W. J. Beenakker
A random-matrix theory is presented for the linewidth of a laser cavity in which the radiation is scattered chaotically. The linewidth is enhanced above the Schawlow-Townes value b…
Excess noise for coherent radiation propagating through amplifying random media
M. Patra, C. W. J. Beenakker
A general theory is presented for the photodetection statistics of coherent radiation that has been amplified by a disordered medium. The beating of the coherent radiation with the…
