Abstract :
Integrated optic polarization independent switches on X-cut Ti:LiNbO3 are realized. An interferometric switch on X-cut Z-propagating LiNbO3 utilizes passive polarization independent intersecting waveguide 3 dB couplers. Polarization independent switches on X-cut Y-propagating LiNbO3 based on polarization converters and intersecting waveguide couplers designed as passive polarization splitters are fabricated and investigated. Devices with an extinction ratio of 25 dB and low fiber coupled insertion losses of <5 dB are presented
