—Polarization-independent fiber-optic filters are presented that replace the polarizers in traditional birefringence filters with a Sagnac interferometer. The performance of these filters is discussed when Solc and Lyot type birefringence combinations are used. A high-order, compound filter combining these two filters is presented, along with experimental(More)
—A high-speed, polarization independent, electrooptic tunable filter was built using a birefringence modulator within a Sagnac interferometer. Switching times less than 0.5 ns were achieved in our experiment for this filter. Application in high-speed wavelength routing was also demonstrated. W AVELENGTH-DIVISION multiplexing (WDM) technology increases the(More)
