IOP Recognizes 4 for Photonics, Optics Research

Facebook X LinkedIn Email
The Institute of Physics (IOP) has recognized four photonics researchers with its 2015 awards.

Eli YablonovitchProfessor Eli Yablonovitch of the University of California, Berkeley, a pioneer in the field of optoelectronics and nanophotonics, received the Isaac Newton Medal, the IOP's highest honor.

Yablonovitch is known for his seminal work on crystal structures that exhibit photonic bandgaps, which limit the propagation of electromagnetic waves at certain frequencies.

In its citation, the IOP credited photonic crystals for a "true paradigm shift in photonics," noting that the structures "are now used in research areas as diverse as quantum computation, nanoscale imaging and sensing, photovoltaics, optical interconnects and high-performance light-emitting diodes."

Nikolay ZheludevThe institute also noted Yablonovitch's work on the problem of solar-cell efficiency, a research field he continues to pursue as group leader at Lawrence Berkeley National Laboratory.

University of Southampton professor Nikolay Zheludev received the IOP's Young Medal in recognition of his work in optical metamaterials, nanophotonics and global leadership.

Zheludev is deputy director of the university’s Optoelectronics Research Centre and directs the Centre for Photonic Materials at Southampton. He is also director of the Centre for Disruptive Photonic Technologies at Nanyang Technological University in Singapore.

Edmund KelleherHe has been involved in development of high-bandwidth, low-intensity optical switching, dispersion control, data processing and optical storage devices. Light harvesting, detectors, nanolasers and components operating across the entire electromagnetic spectrum have also been affected by his work.

The IOP recognized Imperial College London research fellow Edmund Kelleher with the Paterson Medal, its early career award, for contributions to pulse-width and wavelength-versatile fiber-based photonic sources.

Rahul Raveendran-NairKelleher is working to improve the performance and efficiency of fiber lasers while making them smaller and more user-friendly. Such advances could affect instrumentation in several scientific disciplines, including chemical sensing and biomedical imaging.

Rahul Raveendran-Nair of the University of Manchester was awarded the Moseley Medal and Prize for contributions to the understanding of the electrical, optical and structural properties of graphene and its sister compounds.

Nair studied Raman spectroscopy and field emission of carbon nanotube and polymer composites at the Indian Institute of Science in Bangalore before coming to Manchester as a doctoral student. He is now a reader at the university.

Glossary
nano
An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
metamaterial
Metamaterials are artificial materials engineered to have properties not found in naturally occurring substances. These materials are designed to manipulate electromagnetic waves in ways that are not possible with conventional materials. Metamaterials typically consist of structures or elements that are smaller than the wavelength of the waves they interact with. Key characteristics of metamaterials include: Negative refraction index: One of the most notable features of certain...
nanophotonics
Nanophotonics is a branch of science and technology that explores the behavior of light on the nanometer scale, typically at dimensions smaller than the wavelength of light. It involves the study and manipulation of light using nanoscale structures and materials, often at dimensions comparable to or smaller than the wavelength of the light being manipulated. Aspects and applications of nanophotonics include: Nanoscale optical components: Nanophotonics involves the design and fabrication of...
