Abstract

Connection between electromagnetic (EM) signals, as quantum systems, which carry the spectroscopic information, and classical description of EM signals on an input of spectrum analyzers, which action is described in the classical form, is established. The physical substantiation of classical methods of signal theory (ST) is given. Forming EM of signals in form EM radiation and in the form of the electric current, caused by incident EM radiation, is considered at quantum level. Transition to classical approach of EM signals is carried out.

Signal theory methods in quantum electronics

Oleg D. Moskaletz

The necessity of forming of physical signal theory (ST), whch is adequate to quantum electronics (QE) problems, is substantiated, and its elements are stated. The forming of physical ST is based on ST fundamental postulates, quantum Planck postulate, Einstein hypothesis about light quanta and energy expression of electromagnetic (EM) field in quantum electrodynamics. On the base of this statemet mathematical formulation of quantum Planck postulate is given. This formulation is the basic of exact, quantum description of signal in the form of EM field. A relation between exact, quantum description of signal and its classical approximation is established. Thus fundamental problem of quantum and classical physics join is solved for EM field. Obtained results are applied to spontaneous and monochromatic oscillations description.

Physical signal theory as a part of quantum laser theory

Oleg D. Moskaletz

Quantum model of electromagnetic (EM) signals of lasers was suggested and the properties of this model were established. Transfer from quantum model of EM signal to its classical approximation was fulfilled. Strict classical and quantum descriptions of spectral apparatus operation were given and a link between them was established for classical spectrum analyzer (SA). It was shown that this SA transforms time statistics of photons into statistics of their space distribution onto SA output plane, i.e. the link between quantum object (laser signals) and interacting with it SA was established.

Basic characteristics of laser radiation in the quantum and classical form: the new approach to the description of an electromagnetic field

Oleg D. Moskaletz

The necessity of development of the physical signal theory (ST) as component of laser theory is justified, and its principles are stated. These principles include quantum description of signals in the form of electromagnetic (EM) field and their classical representation. The submitted researches are based on Planck hypothesis about discrete levels of energy of EM radiation, Einstein hypothesis about light quantum and Bohr rule of frequencies only, and in so doing Heisenberg indeterminateness principle is taken into account.

Formation and Detection of Signals in the Optical Range

Oleg D. Moskaletz

Based on the quantum postulates of Planck and Einstein, without the use of quantum formalism, a quantum description of optical signals in the form of discrete sequences of instantaneous power and instantaneous values of the electrical component of optical radiation is proposed. The classical approximation of the quantum representation of optical signals is carried out using the methods of signal theory and communication theory. A quantum description of photodetection of optical signals is proposed, within the framework of which the photocurrent is given in the form of a discrete sequence, and its classical description is carried out.

Information Transfer by Optical Signals

Oleg D. Moskaletz

Based on the critical estimation of modern information theory and signal theory, the necessity of developing the physical aspect of signal theory, which is based on an abrupt change in the energy of an optical signal during its formation, is substantiated. It is shown that the inflow of information in time has a quantum nature and is due to the action of the photon production operators. Quantum forms of optical signals were obtained and, based on the methods of communication theory, a transition was made to the classical approximation of an optical signal. The role of the probabilistic nature of quantum processes in the stochastic essence of the optical signal is noted.
