An introduction to nonlinear fiber optics and optical analogues to gravitational phenomena
Dimitrios Kranas, Andleeb Zahra, Friedrich König
The optical fiber is a revolutionary technology of the past century. It enables us to manipulate single modes in nonlinear interactions with precision at the quantum level without…
Analytical description of spontaneous emission of light at the optical event horizon
Maxime J Jacquet, Friedrich König
Quantum fluctuations in curved space-time cause the emission of particles. In order to understand how they may be detected in a laboratory experiment, we consider a moving refracti…
Few-cycle fiber pulse compression and evolution of negative resonant radiation
Joanna McLenaghan, Friedrich König
We present numerical simulations and experimental observations of the spectral expansion of fs-pulses compressing in optical fibers. Using the input pulse frequency chirp we are ab…
Negative frequency resonant radiation
E. Rubino, J. McLenaghan, S. C. Kehr +7
Optical solitons or soliton-like states shed light to blue-shifted frequencies through a resonant emission process. We predict a mechanism by which a second propagating mode is gen…
Evolution of light trapped by a soliton in a microstructured fiber
S. Hill, C. E. Kuklewicz, U. Leonhardt +1
We observe the dynamics of pulse trapping in a microstructured fiber. Few-cycle pulses create a system of two pulses: a Raman shifting soliton traps a pulse in the normal dispersio…
Fiber-optical analogue of the event horizon: Appendices
Thomas G. Philbin, Chris Kuklewicz, Scott Robertson +3
We explain the theory behind our fiber-optical analogue of the event horizon and present the experiment in detail.
Efficient and spectrally bright source of polarization-entangled photons
Friedrich König, Elliott J. Mason, Franco N. C. Wong +1
We demonstrate an efficient fiber-coupled source of nondegenerate polarization entangled photons at 795 and 1609 nm using bidirectionally pumped parametric down-conversion in bulk…
Soliton back-action evading measurement using spectral filtering
F. Koenig, B. Buchler, T. Rechtenwald +2
We report on a back-action evading (BAE) measurement of the photon number of fiber optical solitons operating in the quantum regime. We employ a novel detection scheme based on spe…
