Measurements of refractive index of lithium niobate integrated optical substrate
The measurments of refractive index of lithium niobate integrated optical substrates were performed by means of prism coupling method on a precision goniometer with He-Ne laser. In the experiment, we used the differential technique and a liquid crystal optical rotator. The result shows that the acuracy is of 1×10-4 and the reproducible deviations are less than 5×10-5.
