Dispersion-managed solitons are reviewed within a Gaussian variational approximation and an integral evolution model. In the normal regime of the dispersion map (when the averaged path dispersion is negative), there are two solitons of different pulse duration and energy at a fixed propagation constant. We show that the short soliton with a larger energy is linearly (exponentially) unstable. Th...

A material platform of multilayered surface-plasmon-dielectric-polariton systems is introduced, along with a new physical mechanism enabling simultaneous cancellation of group-velocity and attenuation dispersion to extremely high orders for subwavelength light of any small positive, negative, or zero group velocity. These dispersion-free systems could have significant impact on the development ...

This class of non-negative integer-valued ...

We report on a femtosecond nonlinear amplification fiber laser system using a vector-dispersion compressor, which consists of a transmission grating pair and multipass cell based Gires-Tournois interferometer mirrors. The mirror is designed with nearly zero group-delay dispersion and large negative third-order dispersion. As a result, the third-order dispersion of the compressor can be adjusted...

This paper presents an optimized design of a dispersion compensating photonic crystal fiber (PCF) to achieve gain-flattened Raman performances over S-band using a single pump. Genetic algorithm interfaced with an efficient full-vectorial finite element modal solver based on curvilinear edge/nodal elements is used as an optimization tool for an accurate determination of PCF design parameters. Th...

Manipulation of dispersion curve for enhancing surface plasmon resonance (SPR) detection is proposed. Based on strong correlation between slope of dispersion curve and SPR angle shift, it is confirmed that dispersion curve characteristics can be employed as an analysis tool to evaluate SPR sensor performance and to predict anomalous plasmonic behaviors. Complicated resonance shift in SPR angle,...

This paper establishes a strong link between the dispersion in beliefs among active mutual funds, as revealed through their active holdings (i.e., deviations from benchmarks), and future stock returns. We find that after standard risk adjustments, stocks in the top decile portfolio with large increases in dispersion outperform those in the bottom decile by more than 1% per month. This effect of...

We report a simple and robust Ti:sapphire regenerative amplifier without prepulse stretching. Pulse stretching by positive group-velocity dispersion and negative third-order dispersion are provided by highly dispersive flint glass prisms inside the regenerative amplifier cavity. Using a single-grating compressor, we obtain transformlimited 60-fs Gaussian pulses at up to a 5-kHz repetition rate ...

We demonstrate adjustable negative chirp from a directly-modulated, injection-locked 1.55-μm VCSEL by controlling the injection parameters. Chromatic dispersion tolerance is enhanced by greater than 10X at 10-Gb/s compared to that of a free-running VCSELs. ©2008 Optical Society of America OCIS codes: (230.2035) Dispersion compensation devices, (250.7260) Vertical cavity surface emitting lasers

Optical fiber systems with periodically varying dispersion are the most perspective candidates for high capacity communication lines in the future. An opportunity to assemble the system from pieces of fiber with a dispersion of opposite sign gives an ample freedom to a designer. If systems are completely linear it is possible to design an ideal line, transmitting the pulses to an arbitrary long...
