Paper Abstract

Integrated optical devices in which the modulation characteristic are the same for both the TE and TM modes are of considerable interest for the use in systems incorporating ordinary single mode fiber. A number of polarizaMon-independent devices have been demonstrated, including modulators and couplers formed on a LiNbO3 substrate. However, they suffer from disadvantages of optical damage, Li2O out diffusion and small tolerance of fabricational errors. Earlier work shows that when a laser beam propagates in a Ti:LiNb0301 waveguide along the crystal's Z-axis, the light beam suffers no observable degradation . In this paper we report a novel polarization-independent modulator with optical-damage-immune performance on X-cut Z-propagating LiNbO,.
