In this paper, we propose a novel integrated polarization analyzer sensor (IPAS) made by ion exchange on a glass substrate. It is capable to determine the polarization state of a light beam: elliptical, circular or linear. Furthermore, in the first case, the sensor measures the ellipse's eccentricity and the angle between its major axis and the x-axis of the IPAS (parallel to the glass' top surface). Also, for linear polarization, the angle between polarization direction and the x-axis of the IPAS is measured. The IPAS consists in two Y-junctions that gives three different outputs. The first one is directly one of the two output waveguides of the first Y-junction. The two other outputs are the waveguides following the second Y-junction. Before the latter, a piezoelectric plate creates an artificial anisotropy when it is excited electrically. For each one of the three output signals, a polarizer is inserted between the waveguide's end and a photo-detector. It is demonstrated here that, with adequate signal processing, it is possible to obtain all the information on the polarization state of a light beam.
