Tóm tắt
Multiple-layer perovskite Pb/sub 0.91/La/sub 0.09/Zr/sub 0.65/Ti/sub 0.35/O/sub 3//SrTiO/sub 3/ (PLZT/STO) heterostructures have been grown by pulsed laser deposition (PLD) on [001] MgO/GaAs substrates. The perovskite layers are single phase with 35nm RMS roughness on the top surface. Electrically induced birefringence in the PLZT layers, resulted in both optical phase and optical amplitude modulation. The application of an electric field across the PLZT layers resulted in optical modulation at both the primary and first harmonic frequencies, and direct evidence of the non-linear electro-optic effect.
