[16p-A305-4] Reduction of DC drift in a (Pb,La)(Zr,Ti)O₃ optical modulator

Keywords:PLZT, DC drift

We clarify the mechanism of (Pb,La)(Zr,Ti)O₃ (PLZT) optical modulators due to DC drift. We also report on the reduction of the drift using the thermo-optic effect, which in principle avoids the DC drift.
