Long-lived refractive index changes induced by femtosecond ionization in gas-filled single-ring photonic crystal fibers

Johannes R. Koehler, Felix Köttig, Barbara M. Trabold +2

We investigate refractive index changes caused by femtosecond photoionization in a gas-filled hollow-core photonic crystal fiber. Using spatially-resolved interferometric side-prob…
