Abstract
The measurement of the magnitude and phase of the complex transfer function (CTF) of aperiodically poled lithium niobate waveguide devices using frequency resolved optical gating (FROG) is demonstrated. We investigate the sources of CTF distortions which are related to variations in the spatial distribution of the nonlinear coefficient and phase-mismatch profile and present a method to infer fabrication errors from the CTF discussed.
