"silicon photonic MEMS add-drop filter implemented by postprocessing on standard silicon photonics platform... integration of MEMS in silicon photonics that has been manufactured in a standardized foundry process represents a technology milestone. We demonstrate that photonic MEMS can be integrated alongside established high-performance photonic components on-chip and can be scaled to large volumes"
