High Pressure Gases in Hollow Core Photonic Crystal Fiber:A New Nonlinear Medium
Mohiudeen Azhar, Gordon Wong, Wonkeun Chang +2
The effective Kerr nonlinearity of hollow-core kagome-style photonic crystal fiber (PCF) filled with argon gas increases over 100 times when the pressure is increased from 1 to 150…
Thermo-modulational interband susceptibility and ultrafast temporal dynamics in nonlinear gold-based plasmonic devices
Andrea Marini, Matteo Conforti, Giuseppe Della Valle +7
Starting from first principles, we theoretically model the nonlinear temporal dynamics of gold-based plasmonic devices resulting from the heating of their metallic components. At o…
Ionization-induced asymmetric self-phase modulation and universal modulational instability in gas-filled hollow-core photonic crystal fibers
Mohammed F. Saleh, Wonkeun Chang, John C. Travers +2
We study theoretically the propagation of relatively long pulses with ionizing intensities in a hollow-core photonic crystal fiber filled with a Raman-inactive gas. Due to photoion…
