Nick McKeown

Kenichi Iga

For contributions to Internet router architecture and software-defined networking

For pioneering contributions to the concept, physics, and development of the
vertical-cavity surface-emitting laser

Nick McKeown's high-speed switch and router design and software-defined networking innovations have highlighted a career
dedicated to making the Internet faster, more reliable and secure,
and scalable. An Internet router pioneer, McKeown incorporated
a blend of creative algorithms, deep theoretical analysis, prototype building, and technology transfer to address the performance
bottlenecks that routers faced. He demonstrated that full utilization can be accomplished with input-queued switches using suitable scheduling and worked on combined input-output queued
switches and multicast switch scheduling. This established switch
scheduling as an active field of research. Among his many router
accomplishments was Tiny Tera, a small packet switch with approximately 1 terabit of bandwidth, which included many innovations such as a new circuit for designing a programmable priority encoder and an unusual clock distribution scheme. McKeown
has also led the emergence of software-defined networking
(SDN) as an exciting research area for the Internet community
that has changed how networks are designed, built, and operated
to provide scalability to achieve business agility. SDN gives network owners and operators more control of their infrastructure,
allowing customization and optimization while reducing overall
capital and operational costs. Critical to the success of cloud computing, SDN also allows service providers to create new revenue
opportunities at an accelerated pace. McKeown worked tirelessly for SDN's acceptance, including helping to create the Open
Networking Foundation dedicated to the promotion and adoption of SDN. His efforts resulted in companies including Google,
Amazon, NTT Communications, Microsoft, and China Unicom
deploying SDN in their data centers and networks. McKeown's
contributions to SDN technologies include its architecture and a
solid intellectual foundation supporting it; networking slicing and
virtualization; a protocol-independent programming language;
open-source systems including switches, controllers, compilers,
and apps; and a variety of SDN applications for wired and wireless networks including rigorous network verification and testing.
An IEEE Fellow and member of the U.S. National Academy
of Engineering, McKeown is the Kleiner Perkins, Mayfield, and
Sequoia Professor of Electrical Engineering and Computer Science at Stanford University, Stanford, CA, USA.

Kenichi Iga's pioneering development and continuous improvement of the vertical-cavity surface-emitting laser (VCSEL) has provided an indispensable technology powering applications ranging
from short-range optical communications to high-speed printers
and facial recognition sensors in smart phones. In 1977 Iga proposed the VCSEL and two years later he demonstrated a currentdriven VCSEL at 77K. His goal was to change the direction of the
light output from parallel to the substrate surface as in conventional
edge-emitting lasers to perpendicular to the substrate surface. This
format provided advantages including: a maximum operating power that was not limited by catastrophic optical damage of the exit
aperture as in edge-emitting lasers, lower-cost production because
testing can be performed while the devices are still in wafer form,
and more reliable operation. Iga and his team worked to overcome
challenges in improving the technology and recorded many milestones in VCSEL development. He succeeded in achieving continuous surface emission at room temperature of 850-nm band, which
demonstrated the potential of VCSELs as an engineered semiconductor laser for the photonics community. He achieved the first
room-temperature operation of 1300-nm lasers in 1993. Iga has
demonstrated many unique features of VCSELs, including circular
output beam, ultra-low-threshold current, ultra-low driving power
consumption, dynamic single-frequency operation, and high-speed
modulation, all originating from a short cavity length and a small
cavity volume. He also introduced highly reflective semiconductor
multilayered distributed Bragg reflectors and multi-quantum-well
high-gain media into VCSELs, a proof-of-concept experiment of
wavelength tunable VCSELs, and two-dimensional integration and
operation of VCSEL arrays. The first high-volume commercial use
of VCSELs was as the light source for high-speed LAN. Another
commercial use of VCSELs was in computer mice, where the smalldiameter circular beam and low power consumption made them
ideal for precise pointing functions. The VCSEL arrays developed
by industries world-wide significantly improved the performance
of laser printers and sensors and led to today's smartphones employ
hundreds of VCSEL chips for facial recognition applications.
An IEEE Life Fellow and foreign member of the U.S. National
Academy of Engineering, Iga is Professor Emeritus and former
president of theTokyo Institute of Technology, Tokyo, Japan.

Scope: For exceptional contributions to communications and networking sciences, and engineering.

Scope: For a career of meritorious achievement in electrical science, electrical engineering or the electrical arts.
