    A modified hybrid polymer/silica 1x2 vertical coupler switch (VCS) with a polymer gap layer and a refractive index contrast of 0.008 has been designed, fabricated and characterised. The VCS exhibits low loss, low crosstalk, low switching power, and polarisation insensitivity. Using the 1x2 VCS as a building block, a 1x8 VCS matrix has been implemented.

    Thermo-optic 1 * 2 vertical coupler switches (VCSs) using a hybrid polymer/silica integration technology were designed using a finite element method and a coupled mode method for different refractive index contrasts. The multilayer structures were optimized by thermal analysis. Based on these designs and simulations, hybrid polymer/silica thermooptic 1 * 2 VCSs exhibiting low insertion loss, low crosstalk, low switching power and polarisation independence were demonstrated. Based on this building block, a 1 * 8 VCS has been fabricated.

    A hybrid integration concept has been investigated which combines the advantages of ultra-low loss silica waveguides and low power consumption polymer thermo-optic switches. 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.
