Research Abstract

We have investigated optical properties of self-assembled nanofibers of thiacyanine dye that exhibit an active waveguiding behavior. We have revealed that the mechanism of the waveguiding is the propagation of exciton polaritons along the nanofibers. Using a capability of the nanofibers to manipulate the polaritons at a micron scale, we have constructed miniaturized photonic circuit components such as micro ring resonators by means of micromanipulation.
