Capture time of carriers and photons density in quantum spin lasers

Abstract

Here we describe the structure of two types of quantum spin laser form type quantum dots and wells
according to the bucket model. Then, with according to the structures, we study the laser equations
first in the conventional state, then we propagate the spin state to better gain. That is, carriers and
photons density, with according to the optical gain in both the conventional and spin states, is ratio to
time. In the end, we examine the system in a steady state for a state not captured (t =0ps) and after c
passing (t =2ps)which is captured and photons produced.
