  • Abstract
    We have observed random fluctuations in the local Ti concentration profiles of Ti-diffused LiNbO3waveguides. Calculations show that these variations explain the degraded switch extinction ratio (i.e., crosstalk) and other nonideal characteristics observed in LiNbO3optical switches. We also demonstrate by calculation a new device configuration for eliminating this source of crosstalk.
