Abstract
Experiments on light propagation and electro‐optic modulation have been made for poled LiNbO3 single‐crystal thin films fabricated by the method of epitaxial growth by melting (EGM). The values of the refractive indices are found to be no = 2.200 and ne = 2.184. A phase modulation experiment has been carried out using a Mach‐Zehnder interferometer in the region of 100 Hz‐3 MHz. The electro‐optic coefficients of the film have been determined by the phase‐compensation method, and the values obtained are r33=12 and r13=2.3×10−12 m/V.Keywords
