Photonic circuits based on silicon wire waveguides have attracted significant interest in recent years. They allow strong
confinement of light with moderately low propagation losses. Moreover, the high thermo-optical coefficient of silicon
and the small device size in silicon photonics allow for micro-heaters induced trimming, tuning, and switching with
relatively low power. In this paper, we review our recent progress towards telecom-grade reconfigurable optical add-drop
multiplexers (ROADMs) based on silicon microring resonators. We discuss waveguide and micro-heater design
and fabrication as well as the first demonstration of telecom-grade silicon-microring filters and the first demonstration of
transparent wavelength switching. The reported devices can be employed in numerous optical interconnect schemes.
