Current sign inverter guided by polarization

In this work, there are studied the photodetectors' properties (photocurrent sign inverter) of a linear polarized radiation realized on the basis of anisotropic semiconductors. The photocurrent sign guiding is made by the changing of polarization plane of a linear polarized light wave. It was determined that the inversion point can be moved over the photon energy scale while applying an external displacement. It is shown in the work the influence of the light wave interference on the properties of the photodetector's photosensibility. It was revealed the possibility of creating narrow band photodetectors with sensibility maximums suitable to be used in fiber optic communications. There had been analyzed some cases of using the guided photocurrent sign inverter in which the active elements are the p-n structures, Schottky diodes and twins.
