We present the optimization of a birefringence‐enhanced‐waveguide (BWG)‐based polarization beam splitter (PBS) in a Mach‐Zehnder interferometer (MZI) configuration and analyze the structure‐dependent or polarization‐dependent phase difference, using a delay‐line MZI (DL‐MZI). We fabricate the DL‐MZI using silica‐based planar lightwave circuit technology and, using the DL‐MZI, demonstrate the ability to optimize a PBS by measuring the birefringence of the BWG and structure‐dependent phase offset.
