Flatband Slow Wave in Novel Air-Hole-Array Strip Waveguides
IEEE Photonics Journal, 2009 We design two novel air-hole-array strip waveguides: one with elliptic air holes and the other with sandglass-shaped ones. Simulation results prove that flatband modes with low group velocity and low dispersion can be obtained.

ChandraObservations of Low Velocity Dispersion Groups [PDF]
The Astrophysical Journal, 2005 Deviations of galaxy groups from cluster scaling relations can be understood in terms of an excess of entropy in groups. The main effect of this excess is to reduce the density and thus luminosity of the intragroup gas. Given this, groups should also should show a steep relationship between X-ray luminosity and velocity dispersion.

Period-Timing Bifurcations in a Dispersion-Managed Fiber Laser With Zero Group Velocity Dispersion
IEEE Photonics Journal, 2016 We report on the numerical results of period timing bifurcations in a dispersion-managed (DM) fiber laser with zero group velocity dispersion (GVD).The fiber laser is passively mode-locked by using the nonlinear polarization rotation technique.

Localized Dispersive States in Nonlinear Coupled Mode Equations for Light Propagation in Fiber Bragg Gratings. [PDF]
, 2009 Dispersion effects induce new instabilities and dynamics in the weakly nonlinear description of light propagation in fiber Bragg gratings. A new family of dispersive localized pulses that propagate with the group velocity is numerically found, and its ...

Broader, flatter optical spectra of passively mode-locked semiconductor lasers for a wavelength-division multiplexing source [PDF]
, 1997 Using the time domain master equation for a complex electric-field pulse envelope, we find analytical results for the optical spectra of passively mode-locked semiconductor lasers. The analysis includes the effect of optical nonlinearity of semiconductor

High coupling efficiency to a low dispersion slow light-supporting photonic crystal waveguide [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 In this paper, we design a waveguide on photonic crystal slab for propagation of low-dispersion slow light. By shifting the air holes adjacent to the waveguide, we obtain a photonic crystal waveguide with a group index of 25 in 25 nm bandwidth which ...

High-energy, shock-front assisted resonant radiation in the normal dispersion regime [PDF]
, 2013 We present a simple yet effective theory that predicts the existence of resonant radiation bands in the deep normal group velocity dispersion region of a medium, even in absence of a zero-group velocity dispersion point.
