World Debut for Bookhamt Integrable Tunable Laser Assembly at Ofc/Nfoec 2006


San Jose, CA - March 3, 2006 - Bookham, Inc. (NASDAQ: BKHM), a leading
provider of optical components, modules and subsystems, is to launch its
first integrable tunable laser assembly (iTLA) at OFC/NFOEC next week in
Anaheim, California. The product, based on a monolithic platform, brings
cost effective wideband tunability to Long Haul and regional Metro
applications.

The iTLA will be on display at the Bookham stand (no. 3013), and is based on
the company's fully Telcordia GR-468 qualified wideband tunable laser.
Unlike many other tunable lasers, the Bookham core tunable technology is
built on a monolithic structure with no moving parts. This enables very fast
tuning times and ensures excellent reliability, comparable to that offered
by legacy DFB lasers.

"Bookham is pioneering tunable technology," said Adam Price, Director of
Product Marketing. "We are finding that tunability is becoming a must-have
for our customers, and we are ideally positioned to meet and exceed their
demands. The iTLA is the first of a series of new, vertically integrated
products, which will bring tunability to Long Haul and regional Metro. Our
unique monolithic platform is the ideal building block and 2006 will see
Bookham introduce more exciting new products that will take tunable
integration to the next level.

"Bookham is also able to bring high volume manufacturing knowledge to the
product. With our world-class Indium Phosphide (InP) fabrication facility
and proven off-shore manufacturing capability, we are able to meet volume
demand and provide cost-effective tunable products."

The iTLA complies with the OIF MSA outline and command set to ensure that
customers can integrate it with their systems as quickly as possible. The
product also provides a number of market leading functions, such as low line
width, off-grid tuning, internal SBS dither generation, and a direct input
path for trace tone functionality. Such features provide the flexibility
required for the latest generation of optical networks, particularly where
extended reaches are becoming more common.

Bookham customers are using the iTLA now, and the volume production of the
product is scheduled to begin in the second quarter of this year. The
product will be RoHS 5 compliant.

Senior representatives from Bookham will be attending OFC/NFOEC. To arrange
