This paper describes recent progress on large-scale integrated thermo-optic switches including N X N switches (up to 16 X 16), 1 X N switches (up to 1 X 128), N-arrayed 2 X 2 switches (up to 16-arrayed for optical add/drop multiplexers, which all employ silica-on-silicon planar lightwave circuit technology. These switches exhibit low insertion loss, low polarization loss and high switch extinction ratio. I also describe a trial with the goal of reducing drive power consumption, and report the reliability of the thermo-optic switch modules.
