Optical waveguide materials with high thermal reliability and their applications for high-density optical interconnections

This paper describes newly-developed optical waveguide materials and their future applications in optoelectronic circuit boards. The materials achieved low optical loss and high thermal reliability, as well as good flexibility. We fabricated both flexible and rigid optoelectronic circuit board prototypes using these newly-developed materials, and successfully demonstrated light signal transmission faster than 10 Gbps/ch.
