The primary focus of the Photonics Research Group, headed by Dr. Arash Mafi, is on the application of theoretical, computational, and experimental methods for cutting-edge research in photonics, especially on nonlinear and quantum aspects of guided-wave optics. Guided-wave optics, whether in the form of optical fibers, or as plasmonic and silicon nano-waveguides, is the fundamental platform in device applications in photonics and will always remain at the frontiers of research in photonics. Our group has access to advanced computational and experimental facilities at the Center for High Tech Materials and Department of Physics & Astronomy at the University of New Mexico and benefits from several on-going collaborations with other academic institutions and industry.

Research Interests

  • Quantum and nonlinear behavior of optical waveguides
  • Anderson localization: Wave propagation in random media
  • Linear and nonlinear multimode interference devices
  • Fiber lasers: Radiation balanced lasers; Gain-guided index-antiguided lasers and amplifiers; Beam quality analysis
  • Theoretical, computational, and experimental photonics: Guided-wave and fiber optics
  • Plasmonics and metamaterials.
  • Optical communications

Disorder sharpens optical-fibre images
Disorder sharpens optical-fibre images

To Arash Mafi and colleagues at the University of New Mexico, University of Wisconsin-Milwaukee, Corning Inc. and Clemson University, all in the US, for using the phenomenon of "Anderson localization" to create a better optical fibre for transmitting images.

Disorder in an optical fibre usually blurs transmitted images, but Mafi and colleagues have shown that by putting the right kind of disorder in the right place, the ability of a fibre to transmit sharp images can be enhanced. Indeed, their prototype produced a sharper image than the best available commercial imaging fibres. The technique involves using Anderson localization of light.
