Optical modulation of waveguiding and logic operations play significant roles in highly integrated optical communication components, optical computing, and photonic circuits. Herein, we designed and synthesized spiropyran-functionalized polydiacetylene (SFPDA) microtubes, and realized reversible optical modulation of waveguiding in SFPDA microtubes through fluorescence resonance energy transfer (FRET) between the PDA matrix and spiropyran in open merocyanine (MC) form within the surface of the microtubes. Because of the reversible isomerization characteristics of spiropyran units, we have realized resettable, multireadout logic system that includes OR and INHIBIT logic operations in SFPDA microtube.
