Bookham celebrates 10 year leadership of InP MZ modulator market with shipment of 100,000th unit

SAN JOSE, Calif., – September 3 2007 – Bookham, Inc. (Nasdaq: BKHM), a leading provider of optical components, modules and subsystems, today announced the shipment of its 100,000th InP Mach-Zehnder (MZ) modulator, a milestone that confirms the company’s leadership in this market .

The InP MZ modulator, which has been in production and co-packaged with lasers for over ten years, has accumulated billions of field hours, which demonstrate an extremely high level of reliability of less than 30 FITs. The InP technology is now underpinning the company’s vertically integrated new tunable portfolio, including the MSA compliant integrable tunable laser assembly (iTLA), tunable transmitter assembly (TTA) and tunable small form factor transponder (TSFF).

“InP MZs offer a smaller footprint and lower cost than competing LiNbO3 and GaAs modulators, and have proven their ability to perform in 10Gbit/s metro and long haul applications,” explained Jon White, product line manager, InP MZ and tunable portfolio, at Bookham. “With increasing bandwidth demanding higher line card density, the ability to produce ever smaller components and modules is a critical differentiator. InP offers the ideal platform on which to build the next generation of tunable technology and will enable our future 40Gb/s developments and small form factor products.”

Key products from the Bookham tunable InP MZ portfolio – the TTA and the TSFF – will be demonstrated live at ECOC 2007 later this month on the company’s stand (number 17049).
