Abstract
A silicon based electro-optically active device and method of producing the same, the device comprising: a silicon-on-insulator (SOI) waveguide; an electro-optically active stack within a cavity of the SOI waveguide; and a channel between the electro-optically active stack and the SOI waveguide; wherein the channel is filled with a filling material with a refractive index greater than that of a material forming a sidewall of the cavity to form a bridge-waveguide in the channel between the SOI waveguide and the electro-optically active stack.
