Abstract
A silica-based 2×2 thermo-optic switch with super high delta planar lightwave circuits has been fabricated and used with a low switching power configuration. This switch has two features that aid switching power reduction, namely heat insulating grooves and a thick undercladding. Dependence of the switching characteristics on these features has been examined both theoretically and experimentally. A very low switching power of 45 mW has been achieved
