Abstract: We propose and numerically simulate an optoelectronic compact circular polarimeter. It allows to electrically measure the degree of circular polarization and light intensity at room temperature for a wide range of incidence angles in a single shot. The device, being based on GaAsN, is easy to integrate into standard electronics and does not require bulky movable parts nor extra detectors. Its operation hinges mainly on two phenomena: the spin dependent capture of electrons and the hyperfine interaction between… Show more

“…donde B es un campo magnético externo aplicado, e es la carga del electrón, µ e = 300 cm 2 Vs , µ lh = 50 cm 2 Vs y µ hh = 50 cm 2 Vs [18], son las movilidades de los electrones de la banda de conducción y de los huecos ligeros y pesados de la banda de valencia. El promedio cuántico estadístico de las poblaciones de electrones y huecos están dadas por n y p, respectivamente.…”
