Abstract

The scaling up of silicon photonics towards densely integrated architectures is enabling new optical functionalities and is creating opportunities for emerging applications. This evolution needs to be accompanied by adequate tools for the control of more complex architectures. We report on latest advances on the monitoring and automatic calibration of photonic integrated circuits, self-configuration and tuning of programmable photonic structures, stabilization and locking of the working point against environmental fluctuations. Several strategies are illustrated which may can be used for different circuit topologies, like general-purpose meshes of Mach-Zehnder interferometers and coupled-resonator filters, and can self-adapt to the specific optical signals. Examples of applications are presented in the field of optical signal processing, wavelength-division and mode-division-multiplexing optical communication systems, and free-space-optics imaging.
