A pioneer in the field of ultrafast lasers, Ursula Keller has revolutionized photonics and enabled important scientific and industrial applications in physics, chemistry, and biology. Keller developed the semiconductor saturable absorber mirror (SESAM) for generating ultrashort pulses, which transformed femtosecond lasers from complex devices only used by specialists to reliable instruments suitable for use in any general-purpose scientific laboratory and industrial applications. Most ultrashort lasers today utilize her SESAM mode-locking technology for optical communication, precision measurements, microscopy, ophthalmology, and micromachining applications. Her work has also enabled the optical frequency comb revolution and the invention of the attoclock to resolve electron tunneling a highly debated topic ever since the early days in quantum mechanics. Keller’s development of carrier phase stabilization and frequency comb technology during the 1990s was integral to Hänsch and Hall’s development of laser-based spectroscopy that garnered the 2005 Nobel Prize in Physics.
An IEEE Fellow, Keller is a professor in the physics department at ETH Zürich, Zürich, Switzerland and serves as a director of the Swiss research program NCCR MUST in ultrafast science.
The pioneering efforts of John E. Bowers to advancing hybrid silicon photonics is transforming the way computers connect and how data moves around the world, improving business and consumer experiences via thin strands of fiber with silicon photonics on either end. Bowers developed a bonding process that overcomes the challenges of trying to get light out of silicon and has demonstrated high-quality photonic devices that can be manufactured at high volumes and low cost. His work on the hybrid silicon laser has made photonic integrated circuits in silicon a reality, which is critical to enabling lower-cost, higher-speed, and smaller-footprint devices to meet the bandwidth needs of Internet service providers and to create the data centers of the future.
An IEEE Fellow, Bowers is director of the Institute of Energy Efficiency, University of Santa Barbara, Santa Barbara, CA, USA.
The highly efficient photonic materials developed by Mark E. Thompson have advanced organic light-emitting diode (OLED) technology from a laboratory curiosity to a booming commercial success, providing low-power, high-resolution displays for mobile devices and the newest generation of flat-panel televisions. With a previous device efficiency of only 25%, OLED performance was severely limited. During the late 1990s, Thompson overcame the limitations by introducing iridium and platinum as materials for electrophosphorescent emitters, which through further development now provide practically 100% device efficiency. Less than 10 years after Thompson’s introduction, electrophosphorescent OLEDs were commercialized and are now featured in the very popular Samsung Galaxy smartphones, among other products.
An American Association for the Advancement of Sciences and National Academy of Inventors Fellow, Thompson is a professor with the Department of Chemistry at the University of Southern California, Los Angeles, CA, USA.
Philip Russell’s invention of photonic crystal fiber technology in 1991 opened a completely new field of research in photonics. He continues to be a leading authority in the field and has developed many key aspects of photonic crystal fiber technology, including endlessly single-mode "holey" fibers and hollow-core photonic bandgap fibers. Compared to traditional optical fiber, which is made from solid glass, photonic crystal fiber is typically microstructured with an array of hollow channels that allows tailored control of the light passing through the fiber, providing great flexibility. The fibers have found a wide range of unique applications, many of them pioneered by Prof. Russell, including broadband supercontinuum light sources, high-power fiber lasers, fiber-optic communications, scientific and medical imaging, microscopy, laser beam delivery, sensing, and pressure-tunable gas-based ultraviolet light sources.
Dr. Russell is a founding director of the Max Planck Institute for the Science of Light, Erlangen, Germany and professor of physics at the University of Erlangen-Nuremberg.

Combining a technical and business career, for over 35 years Peter Moulton has worked to develop and commercialize solid state laser and nonlinear optical devices. While at MIT Lincoln Laboratory, in 1982 he invented the Ti:sapphire tunable solid state laser, which revolutionized the field of ultrafast lasers and helped enable a number of significant scientific and engineering advances. These continue, notably in the area of high-harmonic and attosecond-pulse generation. He helped found what has evolved to Q-Peak, Inc. and led a team of researchers that has transitioned many novel materials and devices out of the laboratory for use in a wide variety of applications, including science, medicine, and defense. His efforts in development of high-power visible-wavelength sources have led to a VC-funded spin-out company, Laser Light Engines, now working to enable large-screen, laser-based digital projectors. Moulton continues to innovate, concentrating now on high-power, fiber lasers and ultrafast, mid-infrared laser systems.
An IEEE Life Fellow, OSA Fellow, and member of the U.S. National Academy of Engineering, Dr. Moulton recently retired as the Vice President and Chief Technology Officer of Q-Peak, Inc., Bedford, MA, USA, and remains there as a Principal Scientist. He was awarded the R.W. Wood Prize from the OSA and the William Streifer Scientific Achievement Award from IEEE, both in 1997.
Considered a “father of photonic bandgaps,” Eli Yablonovitch’s pioneering contributions effectively created the new field of photonic band engineering for a variety of advanced technologies. Dr. Yablonovitch originally proposed the idea of photonic bandgaps in 1987 and was the first to successfully demonstrate a photonic crystal in 1991. Dr. Yablonovitch extended the well-known wave function theory of electronic bandgaps in solid-state physics to electromagnetic waves to create the photonic bandgap concept. He then employed an Edisonian approach to discover the first photonic bandgap, demonstrating the electromagnetic equivalent of a semiconductor. That material structure came to be known as “Yablonovite.” He demonstrated that “donors” and “acceptors” could be created within photonic crystals by intentionally introducing defects, just as in semiconductors. Prior to his photonic crystal discoveries, Dr. Yablonovitch introduced the benefit of strain, used in almost all semiconductor lasers, including telecommunications lasers, DVD players, and red laser pointers.
An IEEE Fellow, Dr. Yablonovitch is currently a professor with the Electrical Engineering and Computer Sciences Department at the University of California, Berkeley, and director of the National Science Foundation’s Center for Energy Efficient Electronics Science, which is based at Berkeley.
With contributions spanning over 50 years and still continuing, Amnon Yariv’s work is at the heart of today’s high-speed optical communications systems. He recognized early the importance of optical frequency control for high-speed data transmission and developed the distributed feedback semiconductor laser, which has become the main light source for optical communication networks. With Kam Lau, he was the first to describe the physics that limit modulation speed and demonstrated modulation of semiconductor lasers at microwave frequencies. At the California Institute of Technology his group proposed and demonstrated optoelectronic integrated circuits and co-ushered the fields of phase-conjugate optics and slow light propagation in coupled resonator waveguides. He wrote the first college textbooks in quantum and optical electronics, which helped introduce these subjects as academic disciplines. He founded Ortel Corporation, which pioneered high-speed lasers now commonly used in cable television systems.
