We give an overview on our recent achievements in the field of SOH integration, covering in-device electro-optic coefficients r33 in excess of 200 pm/V, highly efficient Mach-Zehnder modulators, IQ modulators, and modulator-based frequency comb generators
A 40 Gbit/s electro-optic modulator is demonstrated. The modulator is based on a slotted silicon waveguide filled with an organic material. The silicon organic hybrid (SOH) approach allows combining highly nonlinear electro-optic organic materials with CMOS-compatible silicon photonics technology.
CMOS-compatible silicon photonics combined with covers of χ(2) or χ(3)-nonlinear organic material allows electro-optic modulators and all-optical wavelength converters for data rates of 100 Gbit/s and beyond. The devices are not impaired by free carriers.
We demonstrate ultrafast optical signal processing up to bitrates of 170 Gbit/s. Silicon-on-insulator waveguides are defined by CMOS technology. In addition, an organic cladding pro-vides either X(3) or X(2)-nonlinearities that are not impaired by two-photon absorption. With a proper waveguide design, the influence of two-photon absorption in silicon is greatly reduced.
