Nonlinear optical polymers provide a unique and powerful platform for constructing a wide variety of useful optical devices. Historically such polymers have been used in low index contrast, all-organic waveguiding systems, which have a number of significant limitations. With recent progress in silicon photonics, it is now possible to build low-loss, ultra-high confinement optical waveguides within the silicon system. These guides provide high overlap with organic claddings, allowing the creation of a hybrid material platform for nonlinear optics.
