Abstract: The disclosed invention involves the finding that the undesirable variation in the quality of integrated optical devices (IODs) produced using current fabrication procedures is due to compositional variations in, and between, the boules used in these procedures. These compositional variations result in refractive index variations which degrade device performance. The disclosed invention also involves two nondestructive, optical techniques for measuring the refractive index uniformities of the boules and substrates used in fabricating IODs.
