Paper Abstract

Modulators using silicon waveguides with a small (~100 nm) slot in the center of the waveguide filled with an electro-optic polymer can have very low switching voltage. A variety of challenges, including difficulty poling the polymer and difficulty achieving high-speed operation, have so far prevented successful demonstration. Problems poling the polymer may be electrical, such as nonuniform poling fields or too much polymer conductivity compared to the silicon electrodes, or they may be more fundamental. This paper discusses research into one possible improvement in the polymer poling method, which is illumination of the device with an 800-nm-wavelength laser during poling to improve conductivity between the external voltage source and the polymer in the slot.
