Continuum Photonics Selects Applied MEMS (an Input/Output Company) to Develop Its DirectLight Photonic Switch Technology

Houston, TX - November 6, 2001 - Input/Output, Inc. (NYSE: IO), through its wholly-owned subsidiary Applied MEMS, Inc. (Applied MEMS) announced today that it has been selected by Continuum Photonics, Inc. to develop the core micro-electrical-mechanical (MEMS) components of Continuum's DirectLight line of optical switches. Applied MEMS offers world-class, high-volume, automated MEMS fabrication services and custom MEMS packaging services for a wide range of applications. Continuum's innovative and patent-pending DirectLight switching technology offers significant performance, reliability and cost advantages over competing products in optical networking applications.

Dr. Howard Goldberg, Business Development Manager for Applied MEMS said, "We are delighted to be working with Continuum Photonics, a leading-edge technology innovator and solutions provider." Dr. Goldberg continued, "We consider this a unique opportunity to help develop a breakthrough technology, while simultaneously furthering our strategy of becoming the foundry partner of choice for end users of MEMS."

"We were seeking a partner who could work with us through advanced development and proceed directly into production. Applied MEMS was the only one that consistently met all of the business and technology requirements to become our strategic partner," said Dr. Aaron Bent, President of Continuum. Dr. Bent also added, "It was evident that Applied MEMS' expertise in both the development and volume production of complex MEMS structures that require bulk micromachining, made them the obvious choice for developing our DirectLight photonic switch technology."

About MEMS
MEMS are highly miniaturized devices that integrate a number of functions including fluidics, optics, mechanics and electronics on a single silicon chip using techniques similar to traditional integrated circuit process technology. MEMS merges sensing, actuating and computing into miniature systems that enable enhanced levels of perception, control and performance. Example applications include optical switching devices developed for telecommunications; RF devices used in mobile hand held-devices; handheld DNA analysis products for biotechnology companies; advanced sensor technology, such as that used for airbag deployment for the automotive industry; and HDTV quality projection displays on a chip developed by component electronics companies.
