Silicon Organic Hybrid Technology—A Platform for Practical Nonlinear Optics

New CMOS-compatible platforms based on silicon nitride and Hydex for nonlinear optics

“…Another promising approach has involved the use of hybrid integration of SOI nanowires -usually in the form of a "slot" cross-section -with nonlinear organic polymers [53,54]. This approach has the advantage of exploiting the SOI platform for its ability for extremely efficient mode confinement, while at the same time forcing a high proportion of the mode field into slot filled with polymer material, thus exploiting the high nonlinearity and FOM of the polymer.…”

High-Speed, Low Drive-Voltage Silicon-Organic Hybrid Modulator Based on a Binary-Chromophore Electro-Optic Material

“…Drive voltage and device footprint can be strongly reduced by using resonant structures [5], [7]. However, resonant devices feature limited optical bandwidth and their resonance wavelength is particularly prone to temperature fluctuations Silicon-organic hybrid (SOH) integration pursues a fundamentally different approach [8], [9]. Here, light is guided in a silicon waveguide core and nonlinear optical effects of second order are realized by exploiting evanescent interaction of the guided light mode with an organic electro-optic cladding material [10]- [12].…”

High-speed, low-power optical modulators in silicon

“…2(a). There are other structures that work well also [15], but the strip-loaded slot approach combines most of the advantages. In this approach the conductive silicon strip-loads connect the two rails of the slot waveguide with metal electrodes [15,23].…”

“…There are other structures that work well also [15], but the strip-loaded slot approach combines most of the advantages. In this approach the conductive silicon strip-loads connect the two rails of the slot waveguide with metal electrodes [15,23]. Since the slot is typically only 100 nm wide, and both electrical and optical mode almost ideally overlap in the narrow slot, low voltages only are needed to induce a very high refractive index change in the nonlinear material of the slot.…”

“…• Linear-Electro Optic Effect in Cladding: In the so-called silicon-organic hybrid (SOH) approach a conventional silicon-on-insulator waveguide is functionalized with an organic cladding material [15,16]. This way critical fabrication steps can rely on high-yield processes based on CMOS fabrication technology of a silicon-on-insulator (SOI) wafer.…”
