Measurement of Root-Mean-Square Phase Errors in Arrayed Waveguide Gratings
-
Abstract
The interference-based method to measure the root-mean-square phase errors in SiO2-based arrayed waveguide gratings (AWGs) is presented. The experimental results show that the rms phase error of the tested AWG is 0.72 rad.
