Vapor deposited small molecules as an organic nonlinear optical cladding for silicon on insulator technology

We demonstrate a silicon-organic hybrid waveguide fabricated by vapor deposition of a small molecule with a large third-order nonlinearity on a silicon-on-oxide slotted waveguide. The resulting organic cladding has a high third-order susceptibility, high optical quality, and it homogenously fills the slot where the optical mode propagates.
