Phase distribution and linewidth in the micromaser
Physical Review A, 1993The phase distribution function (after Pegg and Barnett, Phys. Rev. A 39, 1665 (1989)] is calculated for the micromaser and the lowest modal phase diffusion constant is compared to the linewidth calculation of Scully et al. [Phys. Rev. A 44, 5992 (19911].

Quantum phase distributions and quasidistributions
Physical Review A, 1992We analyze the relationship between the phase distribution for optical fields derived using phase-operator techniques with that derived from the Wigner phase-space quantum quasiprobability. We show that these two approaches agree for field states dominated by Fock states within a narrow distribution, but differ for cases involving widely separated ...

Distributed Phase Correction Technique
2013 IEEE 19th International Symposium on Asynchronous Circuits and Systems, 2013We broadly use the term phase alignment to encompass the repositioning of edges in one signal with respect to edges in another ``reference'' signal. This paper introduces a phase alignment block, and exemplifies its operation in a couple of separate contexts.

PHASE: A Stochastic Formalism for Phase-Type Distributions
2014Models of non-Markovian systems expressed using stochastic formalisms often employ phase-type distributions in order to approximate the duration of transitions. We introduce a stochastic process calculus named PHASE which operates with phase-type distributions, and provide a step-by-step description of how PHASE processes can be translated into models ...

Canonical and measured phase distributions
Physical Review A, 1995We derive relationships between canonical and measured phase distributions for quantum-oscillator states in the semiclassical regime. First, we extend the formalism for the canonical phase to include external measurement-induced uncertainty. We require that a phase shifter shifts a phase distribution while a number shifter does not change it.

Photon-counting, quantum-phase, and phase-space distributions
Optical Society of America Annual Meeting, 1992We analyze a recent proposal for a new phase operator along with an eight-port homodyne detection experiment1 using phase-space functions. We show that the moments of these sine and cosine operators and, in particular, of the measured dispersion result from a phase distribution obtained from an appropriate Wigner function by integration over radius. We

Quantum phase resolution and phase distribution
Quantum and Semiclassical Optics: Journal of the European Optical Society Part B, 1998We discuss generation and measurement strategies for maximum-likelihood estimation of small phase shifts. We demonstrate that optimal encoding of small phase shifts and optimal measurements of small phase shifts require different states. We also show that states with identical phase resolution may have rather different Pegg-Barnett phase distributions.

Bilateral phase‐type distributions
Naval Research Logistics Quarterly, 1985AbstractIn this article we define a class of distributions called bilateral phase type (BPH), and study its closure and computational properties. The class of BPH distributions is closed under convolution, negative convolution, and mixtures. The one‐sided version of BPH, called generalized phase type (GPH), is also defined.

Distributions of amplitude and phase for bivariate distributions
AEU - International Journal of Electronics and Communications, 2016The distribution of amplitude, its moments and the distribution of phase are derived for thirty four flexible bivariate distributions, including the correlated bivariate normal distribution. The results in part extend those given in Coluccia (2013).

Analysis of Phase Distribution in Phase-Change Nonvolatile Memories
IEEE Electron Device Letters, 2004The phase transformation in chalcogenide-based nonvolatile memories is studied by cell electrical characterization. The cell state (amorphous, crystalline, or mixed) is changed by applying electrical pulses, then the cell resistance R and the current-voltage characteristics are measured.
