    "Applications of Few-Moded Optical Fibers"


    Although single-mode optical fibers are used in numerous applications, restricting a fiber design to strictly single-mode operation significantly constrains the range of available operating parameters, such as the mode effective area and dispersion. By allowing an optical fiber to support more than a single mode, these constraints are relaxed and the range of available design space can be greatly expanded. This talk will present current research in few-moded optical fibers, focusing on design, characterization and applications in optical communication systems, fiber sensors and fiber lasers.

    Speaker Bio(s): 

    Jeffrey W. Nicholson is a distinguished member of technical staff in OFS Laboratories. He received a B.S. in physics from the University of Houston, in Houston, Texas, in 1991 and a Ph.D. in optical sciences from the University of New Mexico in Albuquerque, New Mexico, in 1997. After graduation, he worked as a postdoctoral researcher at Los Alamos National Laboratory in Los Alamos, New Mexico, on femtosecond pulse propagation and characterization. He then moved to Directed Energy Solutions in Albuquerque and worked in the area of high-power, mid-infrared gas lasers. In 2001, he moved to Lucent Technologies’ Bell Laboratories in Murray Hill, New Jersey, in the optical fiber research group. Bell Labs was subsequently sold to Furukawa Electric and became OFS Laboratories in Somerset, New Jersey. His current research interests include high-power fiber lasers and amplifiers, Raman fiber lasers, higher-order mode fibers, hollow-core fibers, and nonlinear propagation effects in fibers.
