Optical-Nanocircuitry

Controlling the flow of light at the nanometer scale has great potential for diverse applications such as integrated optical data communication and on-chip optical moleculasr sensing. We are able to selectively excite and control the propagation of different well-defined modes on two-wire transmission lines. Such modal control can be used to obtain routing of optical pulses according to criteria such as polarization.
