Nano-ceramic Particle Dispersion Photonic Crystal

02 June 2002

Powder technology company Hosokawa and Professor Yoshinari Miyamoto's research laboratory of the Joining and Welding Research Institute, Osaka University, have codeveloped a photonic crystal with high-k nano-ceramic composite particles dispersed in epoxy resin lattices.

Hosokawa developed the composite particle by employing mechanochemical bonding (MCB), the company's unique ultra-fine particle composite technology. The particle delivers a dielectric constant that is 50% higher than conventional fine particles, helping reduce lattice intervals by 20%.

The company and the university group have used the nano-ceramic composite particles in the optical modeling system the group successfully developed in 2001 to create photonic crystal, an artificial grating that is expected to pave the way for the development of terahertz wave-based sensors, and high-capacity milliwave communications devices.

The Ministry of Education, Culture, Sports, Science and Technology has allocated 10 billion yen ($80.0 mil) for a five-year project to develop unexplored optical technologies. Funding will begin in fiscal 2003.
