DESCRIPTION:Siddharth Ramachandran High Dimensional Photonics Lab\, Boston
  University\, Boston\, MA\, USA sidr@bu.edu\; https://sites.bu.edu/ramacha
 ndranlab/\; +1-617-353-9881 Siddharth Ramachandran started his career at B
 ell Labs\, and after a decade in industrial research labs\, returned to ac
 ademia as a member of the faculty at Boston University. He is currently a 
 Distinguished Professor of Engineering at BU. His work on the understandin
 g and development of lightwave devices comprising spatial\, vectorial and 
 topological complexity have been applied in the fields of quantum computin
 g\, optical networks\, brain imaging\, as well as laser based defense syst
 ems. For his contributions\, he has been named a Distinguished Member of T
 echnical Staff at OFS (2003)\, a fellow of Optica (2010)\, IEEE (2019) and
  SPIE (2019)\, an IEEE Distinguished Lecturer (2013-2015)\, a Distinguishe
 d Visiting Fellow of the UK Royal Society of Engineering (2016)\, and a Va
 nnevar Bush Faculty Fellow (2019). He serves the optics and photonics comm
 unity in several capacities\, including\, currently\, as a deputy editor f
 or Optica.\nThis talk will describe the propagation\, control and manipula
 tion of light that manifests spatial complexity. In free space and bulk me
 dia\, such higher order eigenstates of light possess intriguing characteri
 stics such as the ability to carry orbital angular momentum and the abilit
 y to self-heal. Upon confinement\, either by focusing them\, or by guiding
  them in fibers\, even more exotic behaviour\, akin to spin-orbit interact
 ions of confined electrons in atomic and molecular systems\, is observed. 
 Such attributes\, which yield new selection rules for nonlinear optics as 
 well new regimes for light transport\, have spawned applications as divers
 e as microscopy\, classical and quantum networking\, optical computing and
  laser-power scaling. This talk will describe recent applications in fiber
 s after elucidating the fundamental phenomena that make singular light bea
 ms behave dramatically differently from commonly encountered Gaussian-shap
 ed beams of light.
