Abstract
Polarization independent operation of birefringent Fabry-Perot etalon is proposed using polarization conversion mirrors (PCMs) as the cavity mirrors. PCMs, such as Faraday mirrors, rotate the polarization plane by 90° upon reflection thus allowing the same phase accumulation for the two eigenwaves after a roundtrip inside the cavity. Based on that when the cavity is filled with an electrooptic material such as a liquid crystal, polarization independent tunable filtering is obtained.
