Abstract

A simple reflection technique proposed by Teng and Man [Appl. Phys. Lett. 56, 1734 (1990)] as well as independently by Schildkraut [Appl. Opt. 29, 2839 (1990)] for measuring the electro-optic coefficients of poled polymer films is applied to measure the r33 values of both z-cut lithium niobate crystal and diazo-dye-substituted polymer films. The measured r33 value of the lithium niobate crystal is in excellent agreement with the known value, and the observed r33 values of the poled polymer films agree well with those predicted from the second-harmonic-generation measurements.
