Reconfigurability of photonic integrated circuits (PICs) has become increasingly important
due to the growing demands for electronic–photonic systems on a chip driven by emerging
applications, including neuromorphic computing, quantum information, and microwave
photonics. Success in these fields usually requires highly scalable photonic switching units
as essential building blocks. Current photonic switches, however, mainly rely on materials
with weak, volatile thermo‐optic or electro‐optic modulation effects, resulting in large …
