TL;DR: This work demonstrates upconversion-assisted single-photon detection for the 1.55-μm telecommunications band based on a periodically poled lithium niobate waveguide pumped by a monolithic PPLN optical parametric oscillator and finds the results to be consistent with noise photon generation by spontaneous anti-Stokes Raman scattering.

TL;DR: From a comparison with semiclassical simulations, the combined action of the magnetic field of the laser pulse and the Coulomb potential is identified as the origin of the observations.

TL;DR: In this article, the authors demonstrate the first generation of devices that combine the dispersion engineering available in nanophotonic waveguides with quasi-phase-matched nonlinear interactions available in periodically poled lithium niobate (PPLN).

TL;DR: Self-referencing of a Tm-doped fiber oscillator-amplifier system is demonstrated by performing octave-spanning supercontinuum generation in a periodically poled lithium niobate waveguide.

TL;DR: Chirped quasi-phasematched gratings and stimulated Raman scattering are shown to enhance spectral broadening, and the pulse dynamics involved in the broadening processes are explained.
