Journal ArticleDOI
Observation of Backward Pulse Propagation Through a Medium with a Negative Group Velocity
George M. Gehring,Aaron Schweinsberg,Christopher Barsi,Natalie Kostinski,Natalie Kostinski,Robert W. Boyd +5 more
TL;DR: It is demonstrated that the peak of the pulse does propagate backward inside the fiber, even though the energy flow is always in the forward direction.
Journal ArticleDOI
Fiber-Based Slow-Light Technologies
TL;DR: A review of current fiber-based technologies capable of producing slow-light effects is presented, with emphasis on the applicability of these technologies to telecommunications.
Journal ArticleDOI
Reducing pulse distortion in fast-light pulse propagation through an erbium-doped fiber amplifier
Heedeuk Shin,Aaron Schweinsberg,George M. Gehring,Katie Schwertz,Hye Jeong Chang,Robert W. Boyd,Q-Han Park,Daniel J. Gauthier +7 more
TL;DR: With the proper choice of input pulse width, pump power, and background-to-pulse power ratio, the author can obtain significant pulse advancement with minimal pulse distortion.
Journal ArticleDOI
Coupled-resonator-induced transparency in a fiber system
David D. Smith,Nick N. Lepeshkin,Aaron Schweinsberg,George M. Gehring,Robert W. Boyd,Q-Han Park,Q-Han Park,Hongrok Chang,Hongrok Chang,Deborah J. Jackson +9 more
TL;DR: In this paper, the authors observed a cancellation of on-resonance absorption, which can be interpreted as resulting from the destructive interference of the symmetric and anti-symmetric modes of the system, in analogy with electromagnetically induced transparency in atoms.
Journal ArticleDOI
Time-domain measurements of reflection delay in frustrated total internal reflection.
George M. Gehring,Andreas C. Liapis,Svetlana G. Lukishova,Robert W. Boyd,Robert W. Boyd,Robert W. Boyd +5 more
TL;DR: Experimental evidence is presented that the contribution of the Goos-Hänchen shift to tunneling delay is suppressed in frustrated total internal reflection using a Hong-Ou-Mandel interferometer and a liquid-crystal-filled double-prism structure to dynamically change the refractive index of the barrier region.
