Over the next five years, Walsworth's group plans to supply the missing pieces to a secure quantum system. Parallel research groups worldwide investigating rival materials include fellow Harvard professor Lene Hau, who is investigating Bose-Einstein condensates, and Texas A&M associate professor Phillip Hemmer, who is investigating rare-earth-doped insulators.

At the conclusion of his keynote Briere said, Baby steps rule!” In an impoverished 2002-2003, he said, those that can offer simple virus protection, e-mail filtering, voice-over-IP virtual private networks and IP PBX features may rule the day. More complex bandwidth provisioning will be demanded sooner or later, he said, but carriers need to live through the current dry spell first.

The DRWiN wireless LAN antenna operates over in the 2.4 GHz band and is targeted at indoor 802.11-compliant wireless LAN (WLAN) applications. The antenna is equipped with two electronically scanning beams. The antenna offers a 1-ms scanning time, a 360-deg. azimuth scanning range, 6-dBi gain, a 90-deg. elevation beamwidth, and less than –10-dB return loss. The antenna also comes equipped with two MMCX connectors.

Some semiconductor companies have managed to harvest bragging rights from last year's sales and profit drought.

Overall, 2001 was a sad year for almost every semiconductor supplier, with revenue falling an average of 30% and huge losses eroding the hefty gains of the preceding year. However, companies like AMD, IBM, Nvidia, Qualcomm, and STMicroelectronics made significant strides.

For instance, ST began 2001 as the world's sixth-largest chipmaker but ended the year No. 2, behind Intel Corp., which held onto the top position despite a 22% sales decline, according to iSuppli Corp., El Segundo, Calif.

The seismic forces that rocked the semiconductor industry last year left a reshaped competitive landscape with major changes in the ranking among the leading vendors,” said iSuppli analysts Dale Ford and Joe D'Elia last week, in a report. Only three of the top 10 and six of the top 30 companies are ranked in the same position in 2001 as in 2000.”

Toshiba, Texas Instruments, and Samsung slipped a notch each to the third, fourth, and fifth slots, respectively, while NEC dropped to No. 7 from No. 5. Meanwhile, AMD improved its global market position to 10 from 16. Qualcomm was the largest semiconductor company to record revenue growth in 2001. The almost 15% increase, to $1.4 billion, lifted Qualcomm's ranking to 28 from 37. IBM Microelectronics not only moved up tobecome the world's 14th-largest chipmaker, it also upstaged Japan's NEC as the leading supplier of logic ICs.

Fazeli: Without a doubt the tool capabilities force the design methodologies that we use, and based on those design methodologies we've come up with our best practices. I'd also like to echo back requests to the EDA vendors to standardize on interfaces. I think we need to have that capability so that we'd be able to be more flexible on our use of the tools, and the design methodology that we put around them. And also being able to be more flexible as far as bringing point solutions into the overall design environment, and integrating them, and having more flexibility on the choices of the tools that we have for any one given solution.

EE Times: We've reached the end of our time here, so I'd like to thank each of our panelists for all of your very insightful answers.

PARIS —A proposal put together by a Hollywood studio suggests that blue-laser-based high-definition DVD recorders will initially become available as VCR replacements only in the Japanese market. The proposal, written before the last meeting of the DVD Forum and obtained by EE Times, predicted that the rest of the world will have to wait until 2004 or 2005 before seeing blue/red laser players that can play back red-laser-based high-definition content and blue-laser prerecorded HD-DVD media.

At the DVD Forum's steering committee meeting in February, content owners — Warner Bros. in particular — lobbied for a new and more efficient compression algorithm that would allow a full-length movie to fit within the 8.5-Gbyte capacity of today's DVD-9 disk, rather than an immediate migration to blue-laser-based HD-DVD.

But the studio proposal defines a parallel migration path to the full blue-laser-based technology” that the studio expects to be required for the recording of broadcast HDTV signals, as well as for distribution of prerecorded motion pictures with extra materials in the longer term.”
