This polarization transformer is characterized in that the ridge refractive index n r is larger than the substrate refractive index n s , in that the grating period Λ is larger than 0.4-λ/ηο, in that the substrate refractive index n s is smaller than 2.7-n c , and in that the index modulation or corrugation is designed such that, according to the grating mode dispersion equation, the effective index of the TE fundamental grating mode TE 0 is larger than the substrate index n s and the effective index of the TM fundamental grating mode TM 0 is larger than the cover refractive index and smaller than the substrate index n s .

    • The installation for writing large gratings comprises a basis (1), a platform (2) arranged for receiving a substrate (3) covered by photosensitive layer, a phase mask (5) supported by a bridge (4), and a light source associated with means for projecting a light sheet on said phase mask which diffracts this light sheet to form an interferogram in said photosensitive layer so as to define in it a latent grating having a determined period Λ. The platform and the bridge are mounted on the basis so that a relative translation movement can occur between them, said platform or said bridge defining a moving part associated with guiding means along a translation axis (X). This installation comprises sensor means (6, 7) for detecting, during the relative translation movement, a possible yaw between the phase mask and the substrate and further comprises a tilt actuator (52) controlled in function of the detection of said possible yaw and arranged for slightly varying the orientation of the phase mask (5) relatively to said substrate (3) in order to limit said possible yaw under a maximum value equal to Λ/(5L Y ), Lγ being the length of the phase mask along an orthogonal axis (Y) which is greater than 100 mm. The lines of the grating are oriented along this orthogonal axis.
