title: Manipulation of light flows in organic color-graded microstructures towards integrated photonic heterojunction devices.
abstract: Organic color-graded optical waveguides permit low-power photonic analogies of diode/transistors based on the energy-transferred conversion of exciton species. The donor-acceptor junction can asymmetrically output blue/red colors due to the mono-directional energy transfer during light propagation. The switching function of transistors is achieved with an additional gate input by altering the ground state density of acceptors. These organic heterogeneous waveguides are further cascaded together to steer the guided light flows for potential applications in photonic integrations.
