A kind of optical modulators based on doped organic nanowire waveguides that output constant white light from the wire terminus has been demonstrated. When the waveguides are locally excited with a focused laser, bidirectional singlet and triplet energy transfers between the two compounds result in the fluctuations of the singlet and triplet excitons, which induce self‐modulated white light outcoupling from each waveguide despite the doping contents.
