Abstract

We quantitatively track in real-time, the changes in domain statistics with electric field poling, of a ferroelectric Bi ₄Ti ₃O ₁₂ thin film using optical second harmonic generation as a probe. The ferroelectric hysteresis loop is extracted from these optical measurements using a theoretical model. The model also yields ratios of intrinsic nonlinear coefficients such as d ₁₁/d ₁₂ = -3.54 ±0.31, d ₂₆/d ₁₁ = 0.4 ±0.03, and optical birefringence |n _b - n _a| = 0.079 ±0.015.
