Abstract
Abstract An integrated electro-optic birefringent analyzer is disclosed including an electro-optic birefringent medium whose birefringence varies as a function of an associated electric field and a first polarizing medium integrally structured with the electro-optic birefringent medium for detecting the polarization modulation imposed on radiation by the electro-optic birefringent medium.
