Spatial light modulator for optical communication, has polymer dispersed liquid crystal component with eight zones that are addressed to respective electrodes providing non rectilinear pattern to electrode transverse field

摘要

The device has a polymer dispersed liquid crystal (PDLC) component with eight zones that are addressed independently from each other and to respective electrodes (31-38). The electrodes provide a non rectilinear pattern to reduce the sensibility of polarization of the device, due to a transverse electrical field between the electrodes. A retardation plate of anisotropic phase reduces the polarization sensitivity of the device. An independent claim is also included for an application of a device of spatial modulation of a light beam.
