Light that Twists inside fibers

In the last decade, some of the most extensively studied complex light beams are optical vortices, which possess phase or polarization singularities. These beams are interesting because they resemble the emission patterns of single molecule dipoles, or because they potentially represent an infinite set of eigenstates that can be constructed with light. Their use has been demonstrated in, or proposed for, several applications such as higher-dimensional quantum encryption, information capacity scaling, single-molecule spectroscopy and nano-scale imaging.  
 

A recently developed fiber that has a ring-shaped core has enabled their stable generation and propagation in optical fibers for distances of up to kilometres. Since fibers are well known for their ability to offer nonlinear and dispersive tailoring of light, this additionally opens the door to studying and exploiting nonlinear phenomena with such beams. This talk will discuss recent results and intriguing possibilities enabled by fiber propagation of beams that have long been considered interesting, but hitherto unstable in nature.

 

Siddharth Ramachandran, Boston University

 

Dr Siddharth Ramachandran obtained his Ph.D. in Electrical Engineering from the University of Illinois, Urbana-Champaign, in 1998. Thereafter, he joined Bell Laboratories as a Member of Technical Staff and subsequently continued with its spin-off, OFS Laboratories. After a decade in industry, Dr. Ramachandran moved back to academics in 2010, and is now a Professor in the Department of Electrical Engineering at Boston University. 

Prof. Ramachandran’s research focuses on the optical physics of guided waves. He has authored over 200 refereed journal and conference publications, more than 50 invited talks, plenary lectures and tutorials, 3 book-chapters, edited one book, and has been granted 38 patents. For his contributions in the field of fiber-optics, he was named a Distinguished Member of Technical Staff at OFS Labs in 2003, a fellow of the Optical Society (OSA) in 2010, and an IEEE Distinguished Lecturer for 2013-2015. He serves as a topical editor for Optica in addition to serving on numerous conference and advisory committees in the field of optics and applied physics, including as general chair for CLEO-2017.

General Information on NES/OSA Meetings

Cancellations and No-shows:

If the meeting must be cancelled for any reason, we will try to call you at the phone number you leave with your reservation. Official notice of cancellation will be on our answering machine.

We have to pay for the dinners reserved as of the Tuesday before the meeting, so no-shows eat into our cash reserve. If you will not be able to attend, please let us know as early as possible. Otherwise, no-shows will be billed.

Membership Rates:

Regular members $15.00
