Journal ArticleDOI
Dynamics of Cherenkov radiation trapped by a soliton in photonic-crystal fibers.
TL;DR: It is demonstrated that the existence of the self-steepening effect increases the energy of the Cherenkov radiation during the trap while reducing its frequency blueshift.
Journal ArticleDOI
Highly nonlinear all-solid photonic crystal fibers with low dispersion slope.
TL;DR: A fluorine-doped trench-assisted structure is proposed to improve the nonlinearity of photonic crystal fibers (PCFs) and three all-solid highly nonlinear PCFs with low dispersion slope and low confinement loss are designed.
Journal ArticleDOI
All-polarization-maintaining figure-of-9 soliton and dispersion-managed Er-doped fiber oscillators

Multi-carrrier optical communication method and system based on DAPSK
TL;DR: In this article, the authors proposed an optical communication method, comprising of modulation on the obtained bit stream data to generate modulated signals, differential encoding on the modulated signal to generate differentially encoded signals, and converting the encoded signals into electrical signals and mapping the electrical signals onto optical carriers to generate optical signals.
Journal ArticleDOI
Digital linearization of multi-carrier RF link with photonic bandpass sampling
TL;DR: It is shown theoretically that a photonic bandpass sampling link is equivalent to a baseband digital nonlinear link, and then a corresponding linearization scheme for the output signal is proposed, capable of suppressing all types of distortions.
