Dramatic Raman Gain Suppression in the Vicinity of the Zero Dispersion Point in Gas-Filled Hollow-Core Photonic Crystal Fiber
Sebastian T. Bauerschmidt, David Novoa, Philip St. J. Russell
In 1964 Bloembergen and Shen predicted that Raman gain could be suppressed if the rates of phonon creation and annihilation (by inelastic scattering) exactly balance. This is only…
Broadband-tunable LP mode frequency shifting by Raman coherence waves in H-filled hollow-core PCF
S. T. Bauerschmidt, David Novoa, Amir Abdolvand +1
When a laser pump beam of sufficient intensity is incident on a Raman-active medium such as hydrogen gas, a strong Stokes signal, red-shifted by the Raman transition frequency Ω$_R…
Photoionization-induced emission of tunable few-cycle mid-IR dispersive waves in gas-filled hollow-core photonic crystal fiber
David Novoa, Marco Cassataro, John C. Travers +1
We propose a scheme for the emission of few-cycle dispersive waves in the mid-infrared using hollow-core photonic crystal fibers filled with noble gas. The underlying mechanism is…
Modulational instability windows in the nonlinear Schrödinger equation involving higher-order Kerr responses
David Novoa, Daniele Tommasini, José A. Nóvoa-López
We introduce a complete analytical and numerical study of the modulational instability process in a system governed by a canonical nonlinear Schrödinger equation involving local, a…
