We report the first optical waveguide based on perylene diimide (PDI) crystalline microwires . The birefringence, polarized photoluminescence emission, long distance light waveguide as well as electrical‐optical modulation were studied. PDI is a good polymeric electro‐optic material because of its low relative permittivity, low operating voltage, high thermal and photo‐stability, and easy integration on flexible substrates.
