Active phase correction of compact, high resolution silicon photonic arrayed waveguide gratings

Gehl, M.; Trotter, D.; Starbuck, Andrew L.; Pomerene, Andrew P.; Lentine, Anthony L.; Derose, C.

We demonstrate compact silicon photonic arrayed waveguide gratings with channel spacing down to 1 GHz using active phase correction. The relative phase of each path within the device is directly measured using an interferometer, and two methods of phase optimization are implemented and compared.
