Hanbury Brown–Twiss effect with partially coherent electromagnetic beams

Abstract

We derive expressions that allow us to examine the influence of different source parameters on the correlation of intensity fluctuations (the Hanbury Brown-Twiss effect) at two points in the same cross section of a random electromagnetic beam. It is found that these higher-order correlations behave quite differently than the lower-order amplitude-phase correlations that are described by the spectral degree of coherence.

Polarization and Coherence in the Hanbury Brown-Twiss Effect

“…We will apply Equations (18), (22) and (23) to beams that are generated by different types of sources.…”

“…The usefulness of this concept has been questioned in (16). The evolution of the HBT effect during propagation was studied in (17,18).…”

Generalized Hanbury Brown–Twiss effect in partially coherent electromagnetic beams

“…One avenue of investigation on this topic is to explore the possible relationship between the state of polarization of the beam and the behavior of the observable HBT coefficient. Such calculations have been presented in [4][5][6][7][8][9]. In considering the polarization-resolved HBT effect it seems natural to employ the traditional Stokes parameters to describe the state of polarization of the beam.…”

Phase difference enhancement with classical intensity interferometry

“…It seems, however, that more recently the traditional form of intensity interferometry with classical light has received renewed attention in connection with stochastic electromagnetic fields [8][9][10][11][12] and, especially, in connection with classical counterparts of quantum imaging [13], namely, ghost imaging with classical light [14][15][16][17][18], ghost diffraction with classical light [19][20][21][22][23], and quantum-mimetic optical coherence tomography (OCT) [24][25][26].…”
