Ultrafast nonlinear all-optical processes in silicon-on-insulator waveguides
TL;DR: In this article, the authors present an overview of the progress made in recent years in the field of integrated silicon-on-insulator (SOI) waveguide photonics with a strong emphasis on third-order nonlinear optical processes.

TL;DR: The detection of upwardly propagating atmospheric neutrinos by the ice-based Antarctic muon and neutrino detector array (AMANDA) was reported in this paper.
Journal ArticleDOI
Linewidth Sharpening via Polarization-Rotated Feedback in Optically Injected Semiconductor Laser Oscillators
TL;DR: In this paper, the authors combined optical injection and polarization-rotated optical feedback in a semiconductor laser to induce self-referenced periodic output that is widely tunable by simply varying the dc bias points of the system's master and slave.
Journal ArticleDOI
Limit-cycle dynamics with reduced sensitivity to perturbations.
TL;DR: It is demonstrated that at specific operating points, the period-one oscillation frequency is simultaneously insensitive to multiple perturbation sources, including the temperature fluctuations experienced by the master and slave lasers as well as fluctuations in the bias current applied to the slave laser.
Limit-Cycle Dynamics with Reduced Sensitivity to Perturbations (Postprint)
TL;DR: In this article, the authors demonstrate that at specific operating points, the period-one oscillation frequency is simultaneously insensitive to multiple perturbation sources, including temperature fluctuations experienced by the master and slave lasers as well as fluctuations in the bias current applied to the slave laser.
