Abstract
Materials with switchable optical characteristics can enable new types of optical technology that can be tuned or reprogrammed after fabrication. Here, I will present recent results on controlling light on a chip using tunable and programmable materials. New perturbative concepts for altering the flow of light in silicon integrated photonic circuits were initially developed in our lab through ultrafast photomodulation of the silicon waveguide itself. Implementation of reprogrammable photonics using the perturbation approach are now made possible by integrating phase change materials onto the silicon photonics platform. In particular I will be presenting the first results on a new family of new low-loss phase change materials for reconfigurable nanophotonic devices.
