Abstract
We present a closed feedback loop approach to actively control the differential phase shift induced by a thermo-optic modulator in a silicon on insulator platform. We use an on-chip differential phase shift monitoring using integrated balanced photodiodes to generate the feedback signal to control the phase shifter. In addition to the optical circuit we use a control layer to analyse the feedback signal and adapt the electrical power applied in the thermo-optical phase shifter in order to achieve the desired phase shift.
