Which consequence results when imperfections create phase shifts within integrated optical waveguides?

A)Increased bit error rate occurs
B)Reduced group velocity dispersion results
C)Enhanced four-wave mixing is induced
D)Improved signal-to-noise ratio develops

💡 Explanation

Increased bit error rate occurs because the imperfections cause destructive interference which reduces signal strength. Therefore, the effective signal reaching the detector degrades, resulting in detection errors, rather than signal enhancement via constructive interference.
