Programmable photonic integrated circuits (PICs) have recently gained significant interest due to their potential in creating next-generation technologies ranging from artificial neural networks and microwave photonics to quantum information processing. The fundamental building block of such programmable PICs is a tunable 2 × 2 switch, traditionally controlled by the thermo-optic or freecarrier dispersion. Yet, these implementations are power-hungry, volatile, and have a large footprint…
