"Mode Selector v10"

Controlling the flow of optical frequency excitations at the nanometerscale has great potential for diverse applications such as integrated optical communication and on-chip optical sensing. We are able to selectively excited 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.
