Abstract

original image

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.
