Awards & Recognition
- Fellow (International Society for Optics and Photonics (SPIE), 2015)
- Fellow (American Physical Society, 2012)
- Fellow (Optical Society of America, 2019)
- NSF CAREER Award (National Science Foundation , 2006)
- Alexey Belyanin and his collaborator Markus Raschke from CU-Boulder published an article in Nature Nanotechnology which reveals how electrons in graphene respond to an intense optical excitation at the nanoscale and with femtosecond time resolution. The results will help with the design of future nanophotonic devices based on graphene and other two-dimensional materials.
- In recent papers published in PRL and PRB we predicted the existence of bulk and surface electromagnetic modes with highly unusual properties in a special class of topological materials: Weyl semimetals
- In the paper published in Nature, in collaboration with Federico Capasso group at Harvard and Benedikt Schwarz group at TU-Vienna we demonstrated a new generation mechanism of the mid-infrared frequency combs in semiconductor lasers
- In collaboration with researchers in Russia we showed strong optical nonlinearity of graphene resulting from Landau-Zener tunneling of electrons in ultrastrong terahertz fields
- In collaboration with Leon Shterengas group at Stony Brook we demonstrated the first passively mode-locked GaSb mid-infrared semiconductor laser
