Hybrid polymer/silica vertical coupler switch with < -32 dB polarisation-independent crosstalk
Abstract
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.
