GPMWPP is a recent and innovative field for implementing parallel processing in photonic integrated circuits. Light distribution in these circuits is controlled via tunable MZIs using the thermo-optic effect which increases the dependencies on the high-performance blocks due to slower response time and smaller operational bandwidths. To address this limitation, GPMWPPs can be implemented using electro-optic effect offered by BTO devices. However, due to inherent anisotropy associated with BTO correct placement of devices, achieving identical performance for devices in various orientations becomes a challenge. In this work we propose a solution addressing the device placement problem in GPMWPP circuits.
