Application of the Quaternions theory to the analysis of the semimagnetic semiconductor microcavity

The Quaternion theory is applied to a Semimagnetic Semiconductor Microcavity, a Fabry-Perot cavity in which a Quantum Well has been placed in its center. The Optical Scattering Matrix calculus and the Mason's rule are applied to characterize the device, and with the employment of the Pauli decomposition, the different phenomena, like linear and circular birefringence and dichroism, are measured. This analysis is developed for different configurations of the microcavity under the influence of an external magnetic field, which produces very important changes in the polarization properties of the light propagating into the microcavity.
