  • Patent number: 10437082
    Abstract: An electro-optic modulator (EOM) includes a first electro-optic (EO) material configured to receive light. The first EO material has an optic axis that is not parallel to the optical axis of the EOM. The optic axis indicates the direction through the first EO material along which a ray of light passing through the first EO material experiences no birefringence. The EOM also includes a polarization rotator that receives light output from the first EO material. The rotated light passes through a second EO material. The second EO material is positioned in the EOM such that its optic axis is not parallel to the optical axis of the EOM. The second EO material compensates for the birefringence and/or higher-order optical effects of the first material, thus reducing optical transmission errors of the EOM. The EOM may provide a wider field of view for imaging systems.
