The Intrinsic Field of Photons and Applications

Andre Vatarescu

Published May 3, 2021• 0 citations

Abstract

Any photon, regardless of its origin, carries the same optical field profile. This feature and the quantum Rayleigh emissions generate temporally discrete groups of several photons in a resonant cavity incorporating one single quantum dot. A periodic stream of single photons is distorted by high-finesse optical cavities and the quantum Rayleigh spontaneous emission in a beam splitter. Groups of photons emerge from interferometric filters because of multiple internal reflections.

The Quantum Rayleigh Emissions and the Intrinsic Field of Photons Redefining Quantum Correlations

Andre Vatarescu

The quantum Rayleigh scattering of single photons, which is absent from the physical analyses of quantum optic experiments, destroys the mathematical concept of entangled photons. The quantum Rayleigh spontaneous and stimulated emissions provide physically meaningful interpretations for both polarization-based quantum correlations and beam splitter-based anti-correlations by means of groups of identical photons, commonly mistaken for one photon. These can overcome the quantum Rayleigh scattering of single photon in a dielectric medium. The random phases of spontaneously emitted photons play a critical role in obtaining visibility of unity with intensity correlations or number of photons. It is the ratio of physically present photon numbers that determine the visibility rather than a superposition of randomly detected numbers of photons. The intrinsic field of a photon is the same regardless of the optical source. The evolution of the photonic properties of each input of a pure quantum dynamic and coherent number state is described by the Ehrenfest theorem breaking away from the Copenhagen approach of time- and space-independent inputs of mixed density matrices which appear to lead to physically counter-intuitive interpretations.

Instantaneous Quantum Description of Photonic Wavefronts and Applications

Andre Vatarescu

Three physical elements are missing from the conventional formalism of quantum photonics: 1) the quantum Rayleigh spontaneous and stimulated emissions; 2) the unavoidable parametric amplification; and 3) the mixed time-frequency spectral structure of a photonic field which specifies its duration or spatial extent. As a single photon enters a dielectric medium, the quantum Rayleigh scattering prevents it from propagating in a straight-line, thereby destroying any possible entanglement. A pure dynamic and coherent state composed of two consecutive number states, delivers the correct expectation values for the number of photons carried by a photonic wave front, its complex optical field, and phase quadratures. The intrinsic longitudinal and lateral field profiles associated with a group of photons for any instantaneous number of photons are independent of the source. These photonic properties enable a step-by-step analysis of the correlation functions characterizing counting of coincident numbers of photons or intensities with unity visibility interference, spanning the classical and quantum optic regimes

A standard laser produces a coherent state of light with a Poissonian photon number distribution. Generation of single photons on demand is a key requirement for quantum key distribution and quantum information processing systems based on photonic qubits. One of the generation schemes for single photons is to use a single semiconductor quantum dot embedded in a monolithic microcavity. An optical pump pulse or electrical pump pulse generates more than one electron–hole pairs in a quantum dot. Those electron–hole pairs recombine to generate photons one by one via spontaneous emission. The last photon emitted from a quantum dot has a unique wavelength, differing from the other photons, because the multiparticle interaction inside a quantum dot modulates an emission wavelength. One can selectively extract this last photon by a narrow band optical filter, so that single photons are extracted from the system no matter how many electron–hole pairs are injected into the quantum dot initially.
