Polarized Emission and Optical Waveguide in Crystalline Perylene Diimide Microwires

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.
