We have developed a drastically new method of fabricating polymer photonic devices. Utilizing nanoimprinting and ink-jet printing, polymer photonic devices such as modulators and switches have successfully been developed. The room temperature and potentially low-cost manufacturing technology offers several unique advantages, such as 1) good surface quality, 2) etch-free process, 3) environmentally friendly, 4) large-area development, and 5) hybrid integration with printed electronics.
