What do the following key items of modern technology have in
common? The transistor, the fax machine, the talkie, stereo
sound, the laser, the concept and technology of the cellular
phone and the sensor at the back of your digital camera.
And the following bits of fundamental scientific research?
The wave nature of matter, background radiation in the universe
and the quantum Hall effect.
The answer to this quiz is Bell Labs, the venerable
institution whose researchers — people such as
Harry Nyquist and Claude Shannon — were also
responsible for some of the fundamental maths behind the theory
of digital communications.
Bell Labs was set up 85 years ago, in 1925, by the mighty
AT&T, which then ran manufacturing and operations of most
of the US phone business. During the next half-century or so,
the laboratories were responsible for more Nobel prizes for
physics than most countries have won: seven prizes for work
directly at Bell Labs, and four more won by people who spent
some of their career there.
But it’s changed. As part of the break-up of
the old monopolistic AT&T in the 1980s, Bell Labs became
part of the independent manufacturing company, Lucent, which
since 2006 has been half of the merged Alcatel-Lucent.
The person in charge of Bell Labs since 2005 is Jeong Kim, a
specialist in optical communications who has also worked as a
nuclear submarine officer in the US Navy. How has Bell Labs
changed since its ownership changed? "What is changing is the
rest of the world — and the industry is
changing," says Kim, who returned to Lucent to run Bell Labs
after a spell at the University of Maryland. "The change is
something we’re familiar with."
Kim was presiding over the launch of GreenTouch,
Alcatel-Lucent’s bold initiative to reduce the
amount of energy used by communications networks. In the middle
of 2009 a number of Bell Labs engineers decided to draw on the
parallels from the 1930s and 1940s work of Nyquist and Shannon
— who worked out the minimum amount of information
needed to communicate an intelligible signal. Their work is at
the heart of all digital communications.
What, the researchers asked in 2009, is the minimum amount
of energy needed to communicate an intelligible
signal? The answer was surprising: in theory it’s
0.01% — or one ten-thousandth — of what is
used by today’s networks. Even if the number is
multiplied by 10 for reasons of caution, the implication is
that information and communications networks are wasting 99.9%
of their energy.
This project is a sign, he says, of how Bell Labs has a
clear and important role that is distinct from the role of
academic institutions. "Adademia is siloed," says Kim. Bell
Labs allows researchers to work together across disciplines.
"It does require the best of minds from different disciplines.
But if you talk to the researchers from Bell Labs,
that’s what they enjoy," he says.
Bell Labs employs about 1,000 researchers, but no longer all
in a single campus in the US. "More than 50% of our researchers
are foreign born," he says. "We have recruited from the best
universities around the world."
In the old days, Bell Labs would bring them to the US. "Now
we bring Bell Labs around the world, to tap into high quality
researchers. We are sourcing the brightest minds locally."
But there have been other changes. In the old days, when
AT&T was a virtual monopoly in telecoms in the US, much of
the funding was directed towards public interest work, he says.
"Now the funding is by a for-profit entity, so we have to look
after the interests of our funding entity."
However, Bell Labs still believes in open innovation, he
says. "We support open collaboration. We have done throughout
How, though, does the research institution justify its work
to Alcatel-Lucent and its hard-pressed shareholders? "You
create intellectual property," says Kim. The licence revenue on
Bell Labs inventions "easily justifies" the funding that he and
his colleagues receive, he says.
The purpose of Bell Labs today — and in the past
— is "disruptive technology for new markets", he
And what disruptive technologies are researchers working on
today? Work that compares with the transistor and the laser in
revolutionising electronic communications?
"We like surprises," says Kim. "Innovation comes from the
left field, because you’ve not thought about it.
Otherwise people have thought about it, and then it is
incremental, and that’s engineering."
But if the inventions that count are surprises, how do you
choose where to focus your work? "Most of the research projects
are initiated by understanding the pain points," he says. "The
others are started by curiosity. We insist that all our
researchers understand the problems of the industry in their
head," he says.
Asked to offer an estimate of the split between applied and
fundamental projects in Bell Labs, he suggests that 70% are
applied and 30% fundamental. But researchers have to have the
freedom to work on projects that interest them.
"That’s the only way. Otherwise it kills the
Today, Bell Labs has eight locations around the world, in
cities in France, Germany, Belgium, Ireland, India, China and
— most recently — Korea as well as the
And is there work going on that will win further Nobel
prizes? Kim says that there is. "It takes time to be recognised
externally," he says.
And why has Bell Labs won more than any other institution in
the world? "It is the environment," he says. "We are protecting
that environment, with funding support and operational freedom.
If you don’t you can easily destroy it."
