Wigner function for nonparaxial wave fields.
The generalized optical transfer function and the spectral correlation function are investigated for nonparaxial two-dimensional wave fields. The angle-impact marginal of the four-dimensional Wigner function is derived directly. For focused wave fields of semiangle greater than 90 degrees, the spectral correlation function exhibits overlapping and interference. For focused wave fields for which...
متن کاملWigner function of pulsed fields by direct detection.
We present the reconstruction of the Wigner function of some classical pulsed optical states obtained by direct measurement of the detected-photon probability distributions of the state displaced by a coherent field. We use a photodetector endowed with internal gain, which is operated in the non-photon-resolving regime. The measurements are performed up to mesoscopic intensities (up to more tha...
متن کاملWigner function for damped systems
Both classical and quantum damped systems give rise to complex spectra and corresponding resonant states. We investigate how resonant states, which do not belong to the Hilbert space, fit the phase space formulation of quantum mechanics. It turns out that one may construct out of a pair of resonant states an analog of the stationary Wigner function.
متن کاملTwo Methods for Modeling the Propagation of the Coherence and Polarization Properties of Nonparaxial Fields
The propagation of nonparaxial, partially coherent fields may be modeled in many ways. The standard techniques of Huygens-type propagation integrals or plane wave decompositions require quadruple oscillatory integrals that carry a significant computational cost. Two alternative, computationally efficient methods for such modeling are presented here. One uses a discrete nonparaxial basis expansi...
متن کاملκ–deformed Wigner construction of relativistic wave functions and free fields on κ-Minkowski space
We describe the extension of the Wigner‘s infinite-dimensional unitary representations of Poincaré group to the case of κ-deformed Poincaré group. We show that the corresponding coordinate wave functions on noncommutative space-time are described by free field equations on κdeformed Minkowski space. The cases of Klein–Gordon, Dirac, Proca and Maxwell fields are considered. Finally some aspects ...
