Lumera Corporation Continues Impressive Accumulation of Intellectual Property by Receiving Patent for Optical Modulator; New Patent Ensures Lower Optical Loss and Operating Voltage

BOTHELL, Wash.--(BUSINESS WIRE)--Sept. 27, 2005--Lumera Corporation (Nasdaq:LMRA), an emerging leader in the field of nanotechnology, announced today that it received its eighth United States patent from the U.S. Patent and Trademark Office. The technology patented results in optic modulators performing with significantly less optical loss and voltage -- both crucial performance factors for components in optical networks.

The patent joins Lumera's growing intellectual property portfolio directed at a broad range of markets including the high-speed communications and computing industry, biotechnology, and the rapidly increasing proteomics industry. The new optical modulator patented by Lumera has both reduced optical loss and lower operating voltage, and can be fabricated with methods that allow high-volume manufacturing.

“Our expertise in the areas of electro-optic polymers with custom properties, and in device design and fabrication have allowed us to achieve both the reduced optical coupling loss and operating voltage”

The patent is entitled "Polymer Waveguide Devices Incorporating Electro-optically Active Polymer Clads," and has the number 6,937,811.

"Techniques used to reduce both the optical loss and operating voltage tend to fight each other, so typically you have to make a choice between reducing one of the two," said Lumera Chief Executive Officer Tom Mino. "We have found a way to reduce both at the same time -- something that we believe will be of great interest to companies operating optical networks across the world -- and we accomplished this while still having a device that can be manufactured in high volumes."

Electro-optic polymer modulators are typically fabricated with very thin polymer layers in order to reduce the required operating voltage as much as possible. However, these very thin polymer layers create a mismatch with the optical fiber input, which in turn causes high optical loss. Previous efforts to reduce loss typically used one of two methods: squeezing light in the optical fiber to match the very thin polymer stack of the modulator or increasing the thickness of the polymer layers to improve optical loss. In the first case, fabrication of the required parts has proved to be extremely difficult and, in the second case, thicker polymer layers require higher operating voltage.

Lumera solved these issues by using two layers of different electro-optic polymers. The combination of increased thickness and more electro-optic activity lowered both the optical loss and the operating voltage. Lumera previously announced that it had received orders and had shipped production devices of its electro-optical modulators.

"Our expertise in the areas of electro-optic polymers with custom properties, and in device design and fabrication have allowed us to achieve both the reduced optical coupling loss and operating voltage," continued Mino. "The intellectual property and barriers to entry to this type of technology allow Lumera to continue building a strong competitive advantage in the current and future generations of optical devices for the optical networking, microprocessor optical interconnects, and hybrid fiber optic-wireless networks."
