As photonics moves from the single-device level toward large-scale, integrated, and complex systems on a chip, monitoring, control, stabilization of components become critical.We need to monitor circuit non-invasively apply simple, fast, robust feedback control.Here, we show non-invasive monitoring control high-quality-factor silicon (Si) photonic resonators assisted by transparent detector that is directly integrated inside cavity.Control operations are entirely managed CMOS microelectronic bridged Si chip hosts many parallel electronic readout channels.Advanced functionalities, such as wavelength tuning, locking, labeling, swapping, demonstrated.The nature scalability system offer viable solution for arbitrarily reconfigurable circuits aggregating single chip.
