A 1*2 vertical coupler type switch (VCS) has been realised. Preliminary results exhibited a crosstalk of <-23 dB, an insertion loss of 3.5 dB (at 1550 nm) and a switching power of <80 mW.enoptical couplersoptical crosstalkoptical design techniquesoptical fabricationoptical lossesoptical planar waveguidesoptical polymersoptical switchesphotonic switching systemssilicon compoundsthermo-optical effectsthermo-optic vertical coupler switcheshybrid polymer/silica integration technologyhybrid integration conceptultra-low loss silica waveguideslow power consumption polymer thermo-optic switchespolymer thermo-optic switches1*2 vertical coupler type switchcrosstalkinsertion lossswitching power1550 nm3.5 db80 mwsio2621384Thermo-optic vertical coupler switches using hybrid polymer/silica integration technologyjournal article
