Semiconductor laser theory with many-body effects.

Physical Review A, 1989
A theory of a semiconductor laser is developed that includes the many-body effects due to Coulomb interactions. The theory is valid for both 3-D bulk semiconductors as well as quasi-2-D quantum well structures.

Theory of a multimode quasiequilibrium semiconductor laser.

Physical Review A, 1993
This paper gives a simple plane-wave multimode semiconductor-laser theory valid near threshold under the quasiequilibrium assumption that the total field envelope varies little in the intraband scattering times. Subject to these limitations, the theory is able to describe the full many-body effects in the semiconductor medium for a variety of field ...

Theory of noise in semiconductor laser emission

Zeitschrift für Physik A Hadrons and nuclei, 1967
For the complex light field amplitude of a semiconductor laser an equation of a generalized van der Pol oscillator with a fluctuating driving term is derived from first principles. This equation is shown to be valid for optical band-to-band transitions with and withoutk-selection rule. Neglecting the nonlinearity in the saturation higher than of second

Variable thermal conductivity during photo-thermoelasticy theory of semiconductor medium induced by laser pulses with hyperbolic two-temperature theory

Waves in Random and Complex Media, 2021
In this work, the effects of interaction between elastic and plasma-thermal waves are studied in the framework of the hyperbolic two-temperature theory.

Photo-thermoelastic behavior of a functionally graded? Semiconductor medium excited by thermal laser pulses

Physica Scripta, 2022
This work presents an analytical approach to study the photothermal response of a functionally graded semiconducting thermoelastic half-space. The generalized thermoelastic heat conduction theory without energy dissipation is employed to extract the ...

Master-equation theory of semiconductor lasers

Physical Review A, 1995
A master-equation approach to the semiconductor laser is derived. Projection-operator techniques are used to eliminate the fast motion occurring in the system, leading to a description of the system in terms of numbers of electrons and holes, with a fully quantum-mechanical description of the field.

Many-body theory for semiconductor microcavity lasers

Physical Review A, 1995
The influence of many-body, nonequilibrium, and cavity effects on the emission characteristics and carrier dynamics of semiconductor microcavity lasers is investigated. The nonlinear coupled equations for the carrier kinetics and the laser dynamics are derived.
