Broadband chaos generated by an optoelectronic oscillator.
Callan, KE; Gao, Z; Gauthier, Daniel J; Illing, L; Schöll, E (Phys Rev Lett, 20100319)We study an optoelectronic timedelay oscillator that displays highspeed chaotic behavior with a flat, broad power spectrum. The chaotic state coexists with a linearly stable fixed point, which, when subjected ... 
Bunchinginduced optical nonlinearity and instability in cold atoms [Invited].
Gauthier, Daniel J; Greenberg, JA; Schmittberger, BL (Opt Express, 20111107)We report a new nonlinear optical process that occurs in a cloud of cold atoms at lowlightlevels when the incident optical fields simultaneously polarize, cool, and spatiallyorganize the atoms. We observe an extremely ... 
Competition between the modulation instability and stimulated Brillouin scattering in a broadband slow light device
CabreraGranado, E; Calderon, OG; Gaeta, AL; Gauthier, Daniel J; Melle, S; Okawachi, Y; Zhu, Y (Journal of Optics, 20101001)We observe competition between the modulation instability (MI) and stimulated Brillouin scattering (SBS) in a 9.2 GHz broadband SBS slow light device, in which a standard 20 km long singlemode LEAF fibre is used as the ... 
Controllable ultrabroadband slow light in a warm rubidium vapor
Fischer, MC; Gauthier, Daniel J; Greenberg, JA; Zhang, R (Journal of the Optical Society of America B: Optical Physics, 20110101)We study ultrabroadband slow light in a warm rubidium vapor cell. By working between the D1 and D2 transitions, we find a severalnanometer window centered at 788:4nm in which the group index is highly uniform and the absorption ... 
Enhancing lightatom interactions via atomic bunching
Gauthier, Daniel J; Schmittberger, BL (Physical Review A  Atomic, Molecular, and Optical Physics, 20140711)There is a broad interest in enhancing the strength of lightatom interactions to the point where injecting a single photon induces a nonlinear material response. Here we show theoretically that subDopplercooled twolevel ... 
FSBS resonances observed in a standard highly nonlinear fiber.
Gauthier, Daniel J; Wang, J; Zhang, R; Zhu, Y (Opt Express, 20110314)Forward stimulated Brillouin scattering (FSBS) is observed in a standard 2kmlong highly nonlinear fiber. The frequency of FSBS arising from multiple radially guided acoustic resonances is observed up to gigahertz frequencies. ... 
Highfidelity, broadband stimulatedBrillouinscatteringbased slow light using fast noise modulation.
Gauthier, Daniel J; Lee, M; Neifeld, MA; Zhu, Y (Opt Express, 20110117)We demonstrate a 5GHzbroadband tunable slowlight device based on stimulated Brillouin scattering in a standard highlynonlinear optical fiber pumped by a noisecurrentmodulated laser beam. The noisemodulation waveform ... 
Informationtheoretic analysis of a stimulatedBrillouinscatteringbased slowlight system.
Gauthier, Daniel J; Gehm, ME; Lee, M; Neifeld, MA; Zhu, Y (Appl Opt, 20111110)We use an informationtheoretic method developed by Neifeld and Lee [J. Opt. Soc. Am. A 25, C31 (2008)] to analyze the performance of a slowlight system. Slowlight is realized in this system via stimulated Brillouin scattering ... 
Optical precursors in the singular and weak dispersion limits
Cartwright, NA; Gauthier, Daniel J; Jeong, H; Oughstun, KE (JOURNAL OF THE OPTICAL SOCIETY OF AMERICA BOPTICAL PHYSICS, 201008) 
Pulsetrain solutions and excitability in an optoelectronic oscillator
Callan, KE; Gauthier, Daniel J; Rosin, DP; Schöll, E (EPL, 20111101)We study an optoelectronic timedelay oscillator with bandpass filtering for different values of the filter bandwidth. Our experiments show novel pulsetrain solutions with pulse widths that can be controlled over ... 
Refractive changes after descemet stripping endothelial keratoplasty: a simplified mathematical model.
Afshari, NA; Gauthier, Daniel J; Hwang, RY; Wallace, Dana (Invest Ophthalmol Vis Sci, 20110222)PURPOSE: To develop a mathematical model that can predict refractive changes after Descemet stripping endothelial keratoplasty (DSEK). METHODS: A mathematical formula based on the Gullstrand eye model was generated to estimate ... 
Slow light with a sweptfrequency source.
Gauthier, Daniel J; Wang, J; Zhang, R; Zhu, Y (Opt Express, 20101220)ct: We introduce a new concept for stimulatedBrillouinscatteringbased slow light in optical fibers that is applicable for broadlytunable frequencyswept sources. It allows slow light to be achieved, in principle, over ... 
Subwavelength Position Sensing Using Nonlinear Feedback and Wave Chaos
Cavalcante, Hugo; Cohen, Seth; Gauthier, Daniel J (20111216)We demonstrate a positionsensing technique that relies on the inherent sensitivity of chaos, where we illuminate a subwavelength object with a complex structured radiofrequency field generated using wave chaos and nonlinear ...

Transient scaling and resurgence of chimera states in networks of Boolean phase oscillators.
Gauthier, Daniel J; Haynes, ND; Rontani, D; Rosin, DP; Schöll, E (Phys Rev E Stat Nonlin Soft Matter Phys, 201409)We study networks of nonlocally coupled electronic oscillators that can be described approximately by a Kuramotolike model.

United States Patent: Apparatus and Methods Using Highly Optically Dispersive Media
Boyd, Robert W; Gauthier, Daniel J; Shi, Zhimin (20110802)According to the invention, a highly optically dispersive medium is one in which the absolute value of the group index of refraction of the medium is equal to or greater than four. An optical spectroscopic parameter detection ... 
Waveguide QED: Manybody boundstate effects in coherent and Fockstate scattering from a twolevel system
Baranger, Harold U; Gauthier, Daniel J; Zheng, Huaixio (Physical Review A  Atomic, Molecular, and Optical Physics, 20101214)Strong coupling between a twolevel system (TLS) and bosonic modes produces dramatic quantum optics effects. We consider a onedimensional continuum of bosons coupled to a single localized TLS, a system which may be realized ...
