Lumera Awarded Sixth Patent for Optical Modulators; Patented Design Reduces Optical Loss in High-Volume Manufacturing

BOTHELL, WA -- (MARKET WIRE) -- May 23, 2005 -- Lumera Corporation (NASDAQ: LMRA), an emerging leader in the field of nanotechnology, announced today it received its sixth United States patent for its Optical Modulator design. The new patented design reduces optical loss and increases reliability of optical transmissions while allowing for high-volume manufacturing.

This latest patent, titled "Multi-layer Electro-optic Polymers Modulators with Reduced Optical Coupling Loss," joins Lumera's growing intellectual property portfolio directed at a broad range of markets including high-speed telecommunications, biotechnology and proteomics, and wireless networking. The patent number is 6,895,162.

"This new modulator with reduced coupling loss was made possible by our unique abilities to custom produce materials and integrate them into critical networking devices," said Lumera CEO Tom Mino. "Currently, we are the only company that has the facilities and the people to realize such an effort, and we continue to raise the entry barrier by patenting in all areas of the technology."

Optical loss is a crucial performance consideration for telecommunications and data networks due to the high cost of generating optical signals from lasers. Previous efforts have been attempted to address this loss; however, none were reliable in high-volume manufacturing. The new optical modulator design patented by Lumera achieves both objectives: reduction of optical loss and reliability in high-volume manufacturing.

Lumera's new design reduces the optical loss of electro-optic polymer modulators by reducing the optical fiber-to-modulator coupling loss. Previous efforts to improve the high coupling loss involved "squeezing" light within the optical fiber to match the narrow cross sections of the light in the electro-optic polymer modulator.

The techniques required to fabricate device parts that squeeze the light have very low fault tolerance and are not reliable, especially in high-volume manufacturing. By increasing the width of the light path, Lumera's new design is able to improve the optical coupling loss while avoiding the fabrication of parts required to squeeze the light of the optical fiber. The new materials and fabrication techniques used to make the new Lumera modulator are the subjects of separate US and international patent applications.

Lumera CEO Tom Mino said, "We continue to have success in addressing all the challenges of electro-optic polymer modulators, and this again validates our approach of combining material and device design for the whole system."
