The complexity scaling of silicon photonics circuits is raising novel needs related to control. Reconfigurable and programmable architectures need fast, accurate and robust procedures for the tuning and stabilization of their working point, counteracting temperature drifts originated by environmental fluctuations and mutual thermal crosstalk from surrounding integrated devices.
In this seminar, recent achievements on the automated tuning, control and stabilization of integrated photonics architectures are reviewed. Specific focus will be given to the development of on-chip light monitors embedded in key spots of the circuit, low-energy consumption amplitude and phase actuators, advanced techniques for the mitigation of thermal crosstalk, labelling strategies to identify coexisting optical signals inside the photonic circuit, and tuning and locking algorithms.
