The two driving forces for the information revolution are integrated circuit technology (e.g. CPUs, DRAMs) and optical communication.  However, the two technologies have so far have never been integrated into one monolithic technology.  Si has remained the material of choice for integrated electronic circuits, while photonics is based on assembly of many discrete components.  However, if the information revolution is to be sustained, these two technologies would have to merge into one.

We believe that Si photonics, defined as photonics using Si-based materials and Si-compatible processes, can be the answer to such problems.  Thus, it is the goal of our lab to research materials and structures that can enable realization of Si photonics.
