INTERFEROMETRIC POLARIZATION-INDEPENDENT MODULATOR IN LITAO3 Academic Article uri icon

abstract

  • Polarization-independent Mach-Zehnder modulators that utilize the off-diagonal r51 electrooptic coefficient have been produced in LiTaO3. The waveguides are formed by Zn vapor diffusion. Extinction values of 85% at 0.633-m wavelength have been demonstrated for both TE and TM polarizations using a single control voltage and thermal tuning. The relatively large voltage-length product values (VL 15 V-cm) attained in these initial devices is attributed to a weak overlap between optical and electrical field profiles. Electrode alignment and dielectric loading are critical factors for the optimization of device operation. 1990 IEEE
